23 RStudio Tips, Tricks, and Shortcuts

1. Navigate Quickly Between Window Panes

RStudio window panes keep important information about your project accessible. Knowing how to toggle between panes without touching your mouse to move your cursor will save time and improve your workflow. Use these shortcuts to instantly move between panes:

  • : Source editor (your script)
  • : Console
  • : Help
  • : History
  • : Files
  • : Plots
  • : Packages
  • : Environment
  • : Viewer

If you prefer to only have one pane in view at a time, add to any of the above commands to maximize the pane. For example, enter to maximize the R script, notebook, or R Markdown file you are working in.

(Side note: The we show in the shortcuts means “and”, so there’s no need to actually type the key.)

But what if you want to return to the standard four-pane view? No problem! Enter :

Four-Pane View

2. Keyboard Shortcuts

Knowing RStudio keyboard shortcuts will save lots of time when programming. RStudio provides dozens of useful shortcuts that you can access through the menu at the top: .

Another way to access RStudio keyboard shortcuts is with a shortcut! To access shortcuts, type on a Mac, or on Linux and Windows.

Here are some of our favorite RStudio shortcuts:

  • Insert the assignment operator with on a Mac, or on Linux and Windows.
  • Insert the pipe operator with on a Mac, or on Linux and Windows.
  • Run the current line of code with on a Mac or on Linux and Windows.
  • Run all lines of code with on a Mac or on Linux and Windows.
  • Restart the current R session and start fresh with on a Mac or on Linux and Windows.
  • Comment or uncomment lines with on a Mac or on Linux and Windows.
  • Trying to remember a command you submitted earlier? Search the command history from the Console with on a Mac or on Linux and Windows.

There are many more useful shortcuts available, but by mastering the shortcuts above, you’ll be on your way to becoming an RStudio power user!

Another great resource for RStudio shortcuts is the official RStudio cheat sheet available here.

3. Save Time with Code Completion

After you begin typing, a suggestion window will pop up with matching names of functions, objects, and snippets. You can toggle through the list using the up or down arrows and hit to make your selection.

Alternatively, you can utilize a very cool feature called fuzzy matching, which allows you to narrow your search options by entering letters unique to the item you are matching. You do not need to enter all of the letters as long as your entry matches the order of the string.

Let’s take a look at how these code completion methods work. First, we’ll select the function by typing part of the function name, and then use arrows to make the selection. Next, we’ll use fuzzy matching to only enter to narrow our selection further:

Code Completion

4. Quickly Find Files and Functions

In RStudio there’s no need to fumble through your folder structure to find files, and there’s no need to dig for functions! Enter the shortcut to open the window and then use your fuzzy matching skills to narrow your selection:

Open File

5. Customize the Appearance

RStudio offers a wealth of options to customize the appearance to your liking. Under the tab, navigate to to explore the many options available. A nice feature of RStudio is that you can quickly click through the window to preview each theme.

RStudio Theme

6. Easy Links to Documentation

Under the tab in the lower-right window, you’ll find handy links to the online documentation for R functions and R packages. For example, if we search for information about the function using the search bar, the official documentation is returned:

Help Pane

We can also access documentation in the tab by prepending a package or function with , (e.g. ) and running the command into the Console. With either approach, RStudio auto-fills matching function names as you type!

7. Preview and Save Your Plots

Plots generated during an RStudio session are displayed under the tab in the lower-right window. In this window, you can inspect your plots by zooming in and out. If you want to save your plot, you can save the plot as a PDF or image file.

Plot Pane

8. Import and Preview Datasets

RStudio makes it easy to import and preview datasets, no coding required! Under the tab in the upper-right window, there is feature that enables you to import a dataset. This feature supports a variety of formats:

Import Data

You can even preview the dataset before it is loaded:

Import Options

And after the dataset is loaded into RStudio, you can view it with the command, or by clicking the name of the dataset:

View Command

9. Review the Command History with One Click

Earlier, we learned the shortcut to the command history from the console. RStudio also enables you to view your entire command history in the upper-right window by clicking the tab:

History Pane

Save Your “Real” Work. Delete the Rest.

Practice good housekeeping to avoid unforeseen challenges down the road. If you create an R object worth saving, capture the R code that generated the object in an R script file. Save the R script, but don’t save the environment, or workspace, where the object was created.
To prevent RStudio from saving your workspace, open and un-select the option to restore into workspace at startup. Be sure to specify that you never want to save your workspace, like this:

Never Save Your Workspace

Now, each time you open RStudio, you will begin with an empty session. None of the code generated from your previous sessions will be remembered. The R script and datasets can be used to recreate the environment from scratch.

Organize Your Work with Projects

RStudio offers a powerful feature to keep you organized; Projects. It is important to stay organized when you work on multiple analyses. Projects from RStudio allow you to keep all of your important work in one place, including code scripts, plots, figures, results, and datasets.

Create a new project by navigating to the tab in RStudio and select . You have the option to create your new project in a new directory, or an existing directory. RStudio offers dedicated project types if you are working on an R package, or a Shiny Web Application.

RStudio Projects are useful when you need to share your work with colleagues. You can send your project file (ending in ) along with all supporting files, which will make it easier for your colleagues to recreate the working environment and reproduce the results.

But if you want seamless collaboration, you may need to introduce package management into your workflow. Fortunately, RStudio offers a useful tool for package management, , that is now compatible with RStudio projects. We’ll cover next.

Manage Package Versions with renv

We love R at Dataquest, but managing package versions can be a challenge! Fortunately, R package management is easier than ever, thanks to the (“reproducible environment”) package from RStudio. And now, RStudio includes built-in support for .

We won’t get into the details of how to use with RStudio projects in this blog because RStudio provides you with the info you need in the link we provided and in the vignette. But using with RStudio can make R package management much easier, so we wanted to let you know!

The package is replacing the package that RStudio used to maintain.

To use the package with your RStudio projects upgrade to the latest version of RStudio and then install the package with . From there you will have the option to use with all new projects:

Package Management

If you would like to use with an existing project navigate to and check the box to enable :

Package Management

Manage Version Control with GitHub in RStudio

In addition to managing packages in RStudio, you can also use GitHub with RStudio to maintain version control of your projects and R scripts. Check out this article from GitHub and this article from RStudio for all the information you need to integrate Git into your RStudio workflow.

Code Snippets

RStudio offers a very useful feature for inserting common chunks of code, called code snippets. One of our favorites is the snippet that saves you a bit of typing when calling the function to load an R package:

Code Snippets

After you hit return to select the snippet, the function is loaded and the cursor is positioned so you can immediately begin typing the name of the package you want to load:

Library

Our other favorite is the snippet that provides a basic template for writing a custom function. And you can even add snippets of your own! To learn more, check out this article on code snippets from RStudio.

Dig Into the Source Code of a Function

If you’d like to investigate the source code of a function, move your cursor to the function of interest and enter (on a Mac you may need to enter ). This feature even works for functions loaded from any R packages you use.

Function Extraction

If you’ve written a chunk of code that you want to turn into a function, highlight the code chunk and enter on a Mac, on Linux/Windows. A pop-up will appear that will ask you to select a function name.

Extract Function

After the function name is selected, the inputs and code structure needed to turn your code into a function will be added automatically.

Extracted Function

If you have a variable that you would like to extract, highlight the variable and enter on a Mac, on Linux/Windows.

Rename in Scope

At some point, you may need to change the name of a function or a variable used in one of your functions. But using find and replace to do this can be nerve-wracking! Fortunately, RStudio makes it possible to rename in scope. This means your changes will be limited to the variable or function of interest. This will prevent you from accidentally replacing a variable of the same name elsewhere in your code script. To use this feature select the function or variable you want to change and enter on a Mac, or on Linux/Windows.

Scope

Multicursor Support

RStudio supports multiple cursors. Simply click and drag your mouse while holding down on a Mac, or on Windows/Linux.

Cursor Select

Cursor Edit

Use Python with RStudio and reticulate

RStudio supports coding in python. The process to get python up and running within RStudio involves these general steps:

  • Install a base version of Python
  • Install and
  • Create a Python environment in your RStudio project
  • Activate your Python environment
  • Install desired Python packages in your environment
  • Install and configure the R package to use Python

This article provides the code you’ll need for the steps above. We tried it out and were able to run python in RStudio in only a few minutes:

python

Query SQL Using the DBI Package

There are many ways to run SQL queries in RStudio. Here are three of the most popular methods, beginning with the package from R.

You’ll start by generating an in-memory SQL database to use in all your SQL query examples. You’ll generate a SQL database of the well-known “mtcars” dataset. Here’s the code:

Create DB
Now write a SQL query to select all cars from the database with a four-cylinder engine. This command returns a dataframe that you’ll save as :

DBI Query

The dataframe looks like this:
Dataframe

Query SQL in R Markdown or Using an R Notebook

You can achieve the same result in R Notebook or R Markdown by creating a code chunk. Using the connection and database from the first example, run this code:

SQL Query

Specify to save the results of your query to a dataframe. This dataframe is a standard R dataframe that is identical to the one you generated in the previous example. You can use this dataframe in R code chunks to perform analysis or to generate a ggplot, for example:

ggplot code

ggplot

Query SQL with dbplyr

Finally, you’ll use the package to write standard commands that get converted to SQL! Once again, using the connection and database from the first example, you can write a standard call to query the cars with four cylinders, this returns a list object:

dbplyr_1

If you want to see the SQL code that this command was converted to, you can use the function from :

dbplyr_2
When you’re satisfied with your query results, you use the function from to save your results as a dataframe:

dbplyr_3

There you have it! Three different approaches to querying a SQL database with similar results. The only difference between the examples is that the method returns a tibble, whereas the first two methods return a standard R dataframe.

To learn more about querying SQL databases with RStudio, check out this article.

Take it to the Cloud!

RStudio now offers a cloud-based version of RStudio Desktop called, you guessed it… RStudio Cloud. RStudio Cloud allows you to code in RStudio without installing software, you only need a web browser.

Work in RStudio Cloud is organized into projects similar to the desktop version, but RStudio Cloud enables you to specify the version of R you wish to use for each project.

RStudio Cloud also makes it easy and secure to share projects with colleagues, and ensures that the working environment is fully reproducible every time the project is accessed.

As you can see, the layout of RStudio Cloud is very similar to RStudio Desktop:

How can you work faster in R Studio? Do you really want to know?

In this article, I would like to share with you some of my favorite productivity features of R Studio along with their respective shortcuts. As well I will provide information about some other tools and techniques that are useful. I also prepared some visual incentives for you to immediately see some of them in action without the need to go into R Studio.

*Note: Although the gifs have both, PC on top of Mac shortcuts, I am using former in the text, if you are a Mac user most of the shortcuts fall under this dependence:       Ctrl == ⌘ Command  &#;&#;  Alt == ⌥ Option  , but keep in mind that in some cases Ctrl will also be a Control key on Mac which can be confusing. You can always look it up in R Studio with         ⌥ Option+Shift+K (Alt+Shift+K)

Ready? Let’s dig in!

Moving Around

Depending on your work you will be using at least few Rstudio panes on a regular basis. Learning how to change focus between those utilized the most in a quick manner, and without using your pointing device, is a crucial skill for speeding up your workflow. It is achieved by pressing Ctrl (in this case also Control on Mac) and a number corresponding to the desired pane. By adding a Shift to the combination you can also toggle maximize pane for the one that you are switching to at the same time, very handy if you need a broader perspective. The only pane with a different access shortcut is the terminal (Shift+Alt+t). Preset windows: Help(3), History(4), Plots(5), or Environment(8). The two that you will be mostly jumping between frequently are Source Editor(1) and Console (2). Let’s now discuss how you can improve how you work in those. RStudio switching panes shortcut

Work smart, not hard

Usually, the first thing you have to do when you start working is creating some code.  It is crucial to be aware that there are some features that can make it both easier and faster. Even basic tricks can have a great impact after you master using them, especially when combined together.

Code completion

Suggestion list will pop up as you type or can be accessed manually by either pressing Tab or Ctrl + Space. You can adjust those settings in Global Options ->  Code -> Completion, To fill in the suggested phrase you have to press either Tab or Enter, pressing Ctrl + Space with auto-completion list open will close it. You can navigate through the suggestion list with arrows or just hover over the item before filling in.

RStudio code completion

If the list is too long try providing more letters to narrow it down. Beside auto-completing functions and variables, you can also insert snippets. We will get back to discuss those later. It’s good to be aware that auto-completion in R, as well as some search fields, supports fuzzy matching which means that you don’t really have to type all the letters, you can skip any of them as long as those typed are in order and identify what are You looking for. It is especially useful for long function names that you use often, mastering this will allow you to type code much faster. Take note that for fuzzy matching to work with auto-completion, suggestion popup must be already active. In case it doesn’t behave as you would expect, try tweaking it in code completion options.

Paths

If you need to type a path, you can use file path auto-complete which can be brought up by pressing auto-completion shortcut (Tab or Ctrl + Space) from a pair of double or single quotes. 

By default it starts in your working directory, you can navigate from the root location like in shell console starting with “/”, or step up levels in the directory tree by stacking “../”

RStudio paths

Execute and Format code

Executing code in your scripts can be very easy with shortcuts.

  • Ctrl + Enter – Will run current line and jump to the next one, or run selected part without jumping further.
  • Alt + Enter – Allows running code without moving the cursor to the next line if you want to run one line of code multiple times without selecting it.
  • There is also Ctrl + Alt + R to run whole script and
  • Ctrl + Alt + B/E combinations to run it from Beginning to the current line and from the current line to the End.

    RStudio Execute and Format code

If you want to make your code look better quickly try using :

  • Ctrl + I to fix lines indentation
  • Ctrl + Shift + A for complete reformatof the selected part of a code

    RStudio Execute and Format code

If you are not happy with the outcome of those you can always undo the changes. If you look for a more flexible solution for styling check out the styler package.

You may also benefit from remembering those super helpful shortcuts:

Moving lines of code up and down is easily achieved with Alt + Up/Down combination, no need to cut and paste. You can move a single active line that way, or even whole selection. If you need to remove something Ctrl + D will delete current line/selection in no time.

Console History &#; History pane

Everything that you passed to the console doesn’t have to be typed again. Accessing previously executed lines is as easy as navigating with the up arrow and down arrows to cycle between them in chronological order. If you want more visual feedback u can press Ctrl + Up arrow to get a list of last commands. If you combine it with typing in a part of the searched phrase you can narrow it down and easily find even complicated commands that are buried deep in the history. It will also override autocomplete popup if its active. Note: searching console history doesn’t support fuzzy matching so you have to be exact. If you want to clear your console use Ctrl+L, command history will be preserved.

There is also History pane(4) which stores executed commands. It allows searching, easily select the ones you need (pick range with shift or gather individual positions with ctrl). Then easily insert them back into the console (Enter) or source file (Shift + Enter). The latter helps you avoid copying multiple commands from console to source manually which is troublesome due to line signs “>” that get copied along and would otherwise have to be removed.

Dealing with Tabs

If you find yourself working on more than one tab in source editor, you might find it helpful to switch between them with Ctrl+Tab and Ctrl+Shift+Tab combinations. It will allow you to jump to the next and previous tab respectively, there is another way to do this with Ctrl + F11/ F12 if it suits you better. It is also possible to jump to the first or last one by adding Shift to those. Last option that is quite interesting is navigating through tabs in the order they were accessed with Ctrl + F9/F10.

If you get to the point where you have a huge amount of tabs open u can either:

Close All  | Ctrl + Shift + w (+ Alt to keep currently open one),

if you prefer to keep them you can search through your open tabs with Ctrl + Shift + . (be exact, no fuzzy matching here). This search can also be activated with “>>” icon on tabs bar.

Above shortcuts are also accessible from File dropdown menu – this can get in handy while using R studio browser session or simply if you forget them.


This is it for part one. I hope that you like what you just read and picked up something useful. Stay tuned for part 2 of this article with more advanced tips! I will cover some techniques for generating parts of code quicker as well as more code manipulation tricks combined with different ways to search through your projects.

Use RStudio keyboard shortcuts

The R Markdown format can be used with any editor of your choice, as long as R, the rmarkdown package, and Pandoc are installed. However, RStudio is deeply integrated with R Markdown, so you can work with R Markdown smoothly.

Like any IDE (Integrated Development Environment), RStudio has keyboard shortcuts. A full list can be found under the menu . Some of the most useful shortcuts related to R Markdown are summarized in Table

Task Windows & Linux macOS
Insert R chunk Ctrl+Alt+I Command+Option+I
Preview HTML Ctrl+Shift+K Command+Shift+K
Knitr document (knitr) Ctrl+Shift+K Command+Shift+K
Compile Notebook Ctrl+Shift+K Command+Shift+K
Compile PDF Ctrl+Shift+K Command+Shift+K
Run all chunks above Ctrl+Alt+P Command+Option+P
Run current chunk Ctrl+Alt+C Command+Option+C
Run current chunk Ctrl+Shift+Enter Command+Shift+Enter
Run next chunk Ctrl+Alt+N Command+Option+N
Run all chunks Ctrl+Alt+R Command+Option+R

Go to previous chunk/title Ctrl+PgUp Command+PgUp
Show/hide document outline Ctrl+Shift+O Command+Shift+O
Build book, website, … Ctrl+Shift+B Command+Shift+B

Additionally, you can press to spell-check your document. You can also restart the R session by (or on macOS). Restarting regularly is helpful for reproducibility, because results are more likely to be reproducible if they are computed from a new R session. This can also be done through the drop-down menu Restart R and Run All Chunks behind the Run button on the toolbar.

RStudio Shortcuts and Tips

Updated: May by Appsilon Data Science

How to Work Faster in RStudio

In this article we have compiled many of our favorite RStudio keyboard shortcuts, tips, and tricks to help increase your productivity while working with the RStudio IDE. We’ll also provide information about supplemental tools and techniques that are useful for data scientists that work with R.

Here’s what we cover:

*Note: Although we present both options in the gifs (PC and Mac shortcuts), we refer to PC shortcuts in the text. If you are a Mac user most of the shortcuts fall under this dependence:

Ctrl == ⌘ Command  &&  Alt == ⌥ Option

Keep in mind that in some cases Ctrl will also be the control key on Mac which can be confusing. You can always look up the proper shortcuts on RStudio&#;s website or within RStudio itself with:

Option+Shift+K (Alt+Shift+K)

How to Navigate RStudio

Depending on your work, you will use at least a few RStudio panes on a regular basis. Learning how to change focus between those utilized the most in a quick manner, and without using your pointing device, is a crucial skill for speeding up your workflow. It is achieved by pressing Ctrl (in this case also Control on Mac) and a number corresponding to the desired pane. By adding a Shift to the combination you can also toggle maximize pane for the one that you are switching to at the same time, very handy if you need a broader perspective. The only pane with a different access shortcut is the terminal (Shift+Alt+t). Preset windows: Help(3), History(4), Plots(5), or Environment(8). The two that you will be mostly jumping between frequently are Source Editor (1) and Console (2). Let’s now discuss how you can improve how you work in those.

RStudio Moving Focus

How to Use Shortcuts in RStudio

Usually, the first thing you have to do when you start working is creating some code.  It is crucial to be aware that there are some features that can make it both easier and faster. Even basic tricks can have a great impact once you master using them, especially when combined together.

Code Completion

A suggestion list will pop up as you type or can be accessed manually by either pressing Tab or Ctrl + Space. You can adjust those settings in Global Options ->  Code -> Completion.To fill in the suggested phrase you have to press either Tab or Enter, pressing Ctrl + Space with auto-completion list open will close it. You can navigate through the suggestion list with arrows or just hover over the item before filling it in.

RStudio Code Completion

If the list is too long, try providing more letters to narrow it down. Beside auto-completing functions and variables, you can also insert snippets. We will get back to discuss those later. It’s good to be aware that auto-completion in R, as well as some search fields, supports fuzzy matching which means that you don’t really have to type all the letters, you can skip any of them as long as those typed are in order and identify what you are looking for. It is especially useful for long function names that you use often. Mastering this will allow you to type code much faster. Note that for fuzzy matching to work with auto-completion, suggestion popup must be already active. In case it doesn’t behave as you would expect, try tweaking it in code completion options.

Paths

If you need to type a path, you can use file path auto-complete which can be brought up by pressing the auto-completion shortcut (Tab or Ctrl + Space) from a pair of double or single quotes. 

By default it starts in your working directory, you can navigate from the root location like in shell console starting with “/”, or step up levels in the directory tree by stacking “../”

RStudio File Autocomplete

How to Execute and Format Code in RStudio

Executing code in your scripts can be very easy with the following shortcuts:

  • Ctrl + Enter &#; Will run current line and jump to the next one, or run selected part without jumping further.
  • Alt + Enter &#; Allows running code without moving the cursor to the next line if you want to run one line of code multiple times without selecting it.
  • There is also Ctrl + Alt + R to run whole script and
  • Ctrl + Alt + B/E combinations to run it from Beginning to the current line and from the current line to the End.

RStudio Code Execution

If you want to make your code look better quickly try using the following:

  • Ctrl + I to fix lines indentation
  • Ctrl + Shift + A for complete reformat of the selected part of a code

RStudio Reformat Code

If you are not happy with the outcome of those you can always undo the changes. If you look for a more flexible solution for styling check out the styler package.

You may also benefit from remembering these super helpful shortcuts:

Moving lines of code up and down is easily achieved with an Alt + Up/Down combination; there is no need to cut and paste. You can move a single active line that way, or even whole selection. If you need to remove something Ctrl + D will delete current line/selection in no time.

RStudio Moving Code

Console History & History Pane

Everything that you passed to the console doesn’t have to be typed again. Accessing previously executed lines is as easy as navigating with the up arrow and down arrows to cycle between them in chronological order. If you want more visual feedback you can press Ctrl + Up arrow to get a list of last commands. If you combine it with typing in a part of the searched phrase you can narrow it down and easily find even complicated commands that are buried deep in the history. It will also override autocomplete popup if its active. Note: searching console history doesn’t support fuzzy matching so you have to be exact. If you want to clear your console use Ctrl+L,thecommand history will be preserved.

RStudio Console History

There is also a History pane(4) which stores executed commands. It allows search, easy selection of the ones you need (pick range with shift or gather individual positions with ctrl). Then easily insert them back into the console (Enter) or source file (Shift + Enter). The latter helps you avoid copying multiple commands from console to source manually which is troublesome due to line signs “>” that get copied as well and would otherwise have to be removed.

Dealing with Tabs

If you find yourself working on more than one tab in a source editor, you might find it helpful to switch between them with Ctrl+Tab and Ctrl+Shift+Tab combinations. It will allow you to jump to the next and previous tab respectively, there is another way to do this with Ctrl + F11/ F12 if it suits you better. It is also possible to jump to the first or last one by adding Shift to those. Last option that is quite interesting is navigating through tabs in the order they were accessed with Ctrl + F9/F10.

Navigate tabs history back and forward:

RStudio Tabs Navigate Tab History

Jumping tabs:

RStudio Tabs History

Going through tabs back and forth:

RStudio Jumping Tabs

Closing a current tab is easy with Ctrl + w. It is a much better choice than using those small &#;x&#; buttons on the right side of your tabs. If you get to the point where you have a huge amount of tabs open you can:

Close All  | Ctrl + Shift + w (+ Alt to keep the currently open one):

RStudio Closing Tabs

Or if you prefer to keep a lot of tabs open, you can search through your open tabs with Ctrl + Shift + . Be exact! No fuzzy matching here. This search can also be activated with &#;>>&#; icon on tabs bar.

RStudio Blog Tabs Search

The above shortcuts are also accessible from the File dropdown menu &#; this can come in handy while using RStudio browser session or simply if you forget them.

Code Inserting Shortcuts in RStudio

Operators and sections

Let’s start with some shortcuts that are easy and very useful! If you want to speed up typing the most common operators you will definitely love these:

Alt + (-) for inserting assignment operator <-

and

Ctrl + Shift + M for a magrittr operator (aka pipe)  %>%

The nice thing about those two is the fact that spaces are inserted along with the operator.

Ctrl + Shift + R  is an easy way to create foldable comment sections in your code.

It&#;s worth it to know about the appliance of those sections for code externalization with knitr:read_chunk() function. If you want to know more about that check the details.

You can open/collapse those comment sections (as well as other kinds of sections e.g. inside curly braces {} or in Rmd) with

Alt + L &#; collapse

Alt + Shift + L &#; open

To collapse or open all sections, instead of the active one, just replace L with O on those shortcuts.

RStudio Insert Code

Function/Variable Extraction

If you have written a statement that you would like to convert into a function, don’t start from scratch. Select it and try Ctrl + Alt + X &#; shortcut for “extract into function”. You only need to provide the function name, all necessary inputs will be filled automatically. There is also a similar shortcut for a variable extraction available with Ctrl + Alt + V. Here you have an example of usage.

RStudio Extract Functions and Variables

Renaming in Scope

If you have to change a variable name in multiple places but you are afraid that &#;find and replace&#; will mess up your code, you should be aware that it is possible to rename in scope only. It is achieved by selecting the function or variable we want to change and press Ctrl + Shift + Alt + M.

It will select all occurrences in scope, you will have to just type a new name.

Yes, the shortcut is long, but it can be helpful. I find it to be easier to remember as an extension of the magrittr operator shortcut, so Pipe+Alt. 🙂

RStudio Rename in Scope

Using Code Snippets in RStudio

Are you tired of writing the same chunks of code over and over and having to remember all of the brackets and required parameters for functions? A great way to avoid writing so much, especially a common code, is to use code snippets.

What are code snippets?

Code snippets are pieces of re-usable boilerplate code.

RStudio Shiny App Code Snippet

Snippets are perfect for automatically inserting boilerplate code and avoiding the duplication of simple tasks. If you are looking for a way to speed up writing large parts of code when time is limited (e.g. live coding during a presentation), code snippets can be very useful.

How do I use code snippets?

Snippets can be recognized on your auto-completion list by a {snippet} tag.

Write the snippet name, press Shift + Tab, or Tab twice to use it. If your input is needed to complete it &#; just fill out positions with elements that are important. You can cycle through them with Tab.

Some of the snippets which are available by default include:

  • Declarations &#; lib, req, fun, ret, mat
  • Loops &#; for, while, switch
  • Conditionals &#; if, el, and ei for conditionals
  • Apply family functions &#; apply, lapply, sapply, etc.
  • S4 classes/methods definitions &#; sc, sm, and sg.
  • Shiny App template &#; shinyapp

RStudio Code Snippets

And that&#;s just for R! There are also snippets for other languages and it is very easy to customize and define your own!

You might have noticed that I used insertOperatorsExample, a very simple custom snippet I created on the first gif showing operator shortcuts.

How to Create Custom Code Snippets in RStudio

For customizing or creating your own snippets use Edit Snippets button under Snippets section in

Tools -> Global Options ->  Code

To understand better how you can create your snippets let’s take a look at a matrix and function snippets declarations code as an example.

$ is used as a special character to denote where the cursor should jump after completing each section of a snippet. Inside the brackets, we have a field index (order in which the cursor will jump after pressing tab), 0 is used as the last field, and the text after a colon is used as information on what should be placed in that spot. In order to insert a literal “$” inside a snippet, it must be escaped as \$.

Snippets, besides generating code templates, can also run R code. It allows you to create dynamic snippets. By using `r expr` anywhere in your snippet your R code will be executed when the snippet is expanded, and the result inserted into the document.  

As an example take a look at the timestamp snippet declaration that is available by default.

 

 

It runs a paste function to insert a comment with a current date into code. Its execution resolves into something like this:

Equipped with this knowledge, let&#;s quickly create a custom snippet for inserting pipe, but instead of a space we will have a new line right after it:

RStudio Pipe Snippet

Using Search in RStudio

So, if you don’t have a lot of code yet, you have the tools to quickly generate it.

The next question is then, how to find things that you are looking for quickly.

There are several available options for search that you can use.

Go to file function Ctrl + (.) allows you to quickly search your project for a file or function and jump directly to it. It supports fuzzy matching so it’s easy to find what you need.

RStudio Searching

If you need more robustness, use Ctrl + Shift + F to call the Find in Files window which allows you to search through files in a directory that you can specify (even outside the project). You can jump between elements you found by double-clicking them in the Find in Files window which opens next to the console.

RStudio Searching 2

If you want to search only inside an active source tab you can use the find bar with Ctrl + F which allows several additional options like replacing texts and searching inside a selected part of code only. It can also be useful for multiple cursor editing &#; see the section below.

We have already covered more methods inpart 1 &#; search within console history and searching through your tabs. You can refer to it if you want to get more details on those.

How to Edit With Multiple Cursors in RStudio

In RStudio, it is possible to write and edit in more than one place at a time. There are a couple of ways to create multiple cursors. You can press Ctrl + Alt + (Up/Down) to create a new cursor in the direction in which you press. If you want to quickly select more lines use Alt and drag with the mouse to create a rectangular selection, or Alt + Shift and click to create a rectangular selection from the current cursor position to the clicked position. 

This way of editing may look intimidating  at first, and may not be easy to operate initially. However, knowing it is there can save you time when you encounter repetitive multi-line tasks. Try playing around with using multiple cursors and see how it feels.

Below you can see an example of how using multiple cursors might look:

RStudio Multiple Line Editing

Another way is to use the Find/Replace toolbar from the previous paragraph to place multiple cursors. Just search a phrase and press the All button to select all matching items. It will create a cursor for each matching phrase. If you don’t want to search throughout the entire file you can also limit the area for a searched phrase by selecting a part you are interested in and checking the box with the “In selection” option.

RStudio Multiple Line Editing

How to Use R Addins

R Addins are a broad topic that could fill a blog post on their own. We just want to give you a brief introduction to this concept.

What are R Addins?

R Addins make it possible to execute R functions in an interactive way right from within the RStudio. Addins are distributed as R packages and can be launched either through the Addins dropdown on the toolbar or through assigned keyboard shortcuts.

We can distinguish two types of addins. Those are text macros and Shiny gadgets. Text macros insert text into the console / source pane or can transform text within the source pane.  Shiny gadgets are interactive Shiny applications launched inside RStudio which may also perform transformations like text macros, but their possibilities are much more extensive.

Test Out Some Addins

To quickly try addins you can install some examples from RStudio Github.

devtools::install_github(&#;rstudio/addinexamples&#;, type = &#;source&#;)

It will give you a text macro for inserting %in% operator as well as three shiny gadgets for a small sneak peek of what&#;s possible.

As I mentioned, you can assign a keyboard shortcut to an addin the same way as you do it with regular shortcuts.  You can find them easily by filtering “Addin&#; (all of them have their scope set like that).

Make Your Own R Addins

If you want to check out more of them try the addinslist package by Dean Attali.

If you would you like to create your own addins, you can find more information on how to do ithere.

Bonus RStudio Tips 

Tip: Use vim Settings

Keep your hands in one place! It’s a powerful method for programmers. Examples: dd to delete the whole line, 7dd to delete 7 lines, navigate, macros, jumping around whole words instead of letters.

Tip: Use .RProfile

When you develop an R package, it’s useful to load frequently used dev packages in the .RProfile file (placed in the main package directory). For example:

This way you can use functions like `test(), check()` without specific package reference or loading the packages on your own.

Tip: Increase Security with .Renviron

Do not keep credentials inside your project code. A good practice is to keep them “gitignored” inside the .Renviron file:

And use a variable in the code with `Sys.getenv(“db_password”)`.

Tip: Use Docker

If you want to keep a consistent environment for your project development within a team, use a dockerized version of RStudio (https://hub.docker.com/r/rocker/rstudio/).

Tell Us About Your RStudio Tips

There is obviously plenty more to explore on the topic of improving your RStudio workflow, and we hope you are inspired to pursue further exploration and experiments on your own. If you end up with something useful as a result &#; be it a code snippet, an addin or just something useful that we did not mention her, why not share it as a comment below? We’ll be updating this page regularly with more RStudio tips.

10 RStudio keyboard shortcuts that will change your life!

R Markdown

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see http://rmarkdown.rstudio.com. A useful guide to help you get started can be found here.

Rmarkdown is a great way to perform reproducible research and generate reports.

Super brief overview

  1. Create a new Rmd file. In RStudio
  2. When you have a Rmd file open in RStudio there’s a button up the top of the source window. You click that button to turn the markdown into HTML (or PDF or Word).
  3. Text and R code can be combined in the Rmd file. Code chunks begin with three back ticks followed by , the (optional) chunk name and any arugments: or . The chunk also ends with three back ticks . Examples can be seen in the template that opens along as a new file in RStudio.

Including Plots

You can embed static plots in an rmarkdown document without doing anything special. Important chunk options are and to set the figure width and height for example .

Chunk options

Some useful chunk options:

  • makes the R code more readable (proper spacing)
  • hide the results of the chunk output (i.e. don’t show them)
  • hold the results of the chunk output until all commands in the chunk have been run
  • don’t show any warning messages (e.g. when ggplot2 drops observations)
  • don’t show any messages (e.g. when packages load)
  • you can name your chunks with text immediately after the . This can be particularly useful when errors pop up as it makes it easier to identify which chunk the error occurs in.
