Requires R.
We recommend using this extension with radian, an alternative R console with multiline editing and rich syntax highlighting.
- Execute the following command in VS Code to display the extension installation screen. 「Command + Shift + x」 Enter 'java' on the search screen and select 'Java Extension Pack' to install If the screen below is displayed as a result of installation, select 'Download manually'.
- Download Visual Studio Code for Mac & read reviews. See if VS Code is worth your time. If you need a source code editor, this could be the one for you.
Installation Download Visual Studio Code for Mac. Double-click on the downloaded archive to expand the contents. Drag Visual Studio Code.app to the Applications folder, making it available in the Launchpad. Updated to VS Code 1.0!!! Before doing something with Code, we need to install it. You can do it visiting site where Microsoft publishes.
Usage

R Session Watcher (Experimental)
This experimental feature is still under development and the behaviormay change without notice. Please file an issue here if you experience problems or have any suggestions.
An opt-in experimental R session watcher is implemented to support the following features:
- Watch any R session
- Show value of session symbols on hover
- Provide completion for session symbols
View()
any objects including data frames and list objects- Show plot output on update and plot history
- Show htmlwidgets, documentation and shiny apps in WebView
- Execute RStudio addins
Basic usage
To enable this feature, turn on
r.sessionWatcher
in VSCode settings, reload or restart VSCode, and the session watcher will be activated automaticallyon R sessions launched by vscode-R via R: Create R Terminal
command.If you previously appended the
source(..)
line to ~/.Rprofile
, you may safely remove it since the configuration for basic usage is automated. It isnow only necessary for advanced usage described below.Advanced usage (for self-managed R sessions)
For advanced users to work with self-managed R sessions (e.g. manually launched R terminal or started in
tmux
or screen
window), some extraconfiguration is needed. Follow the steps below to make R session watcher work with any external R session:- Turn on
r.sessionWatcher
in VSCode settings. - Edit
.Rprofile
in your home directory by running the following code in R: - Append the following code to the file:
- Restart or Reload Window in VSCode
If the workspace folder you open in VSCode already has a
.Rprofile
, you need to append the code above in this file too because ~/.Rprofile
will notbe executed when a local .Rprofile
is found.The script only works with environment variable
TERM_PROGRAM=vscode
. the script will not take effect with R sessions started in a tmux
or screen
window that does not have it, unless this environment variable is manually set before sourcing init.R
, for example, you may insert a line Sys.setenv(TERM_PROGRAM='vscode')
before it.Available functions and options
When the session watcher is initialized on session startup, a local environment named
tools:vscode
is attached and the following functions are made available for user to interoperate with VSCode:All WebView-related functions have a
viewer
argument which could be one of the values defined invscode-api#ViewColumn, .e.g.'Active'
(current editor), 'Two'
(editor group 2), or 'Beside'
(always show besides the current editor).The following options are available for user to customize the session watcher functionality and behavior:
The first values are the default and all subsequent values after
|
are available choices.The 'Two' | 'Active' | 'Beside'
are popular values from ViewColumn
to specify which view column should the corresponding tab appears in VSCode.RStudio addin support
The session watcher allows RStudio addins to be executed via an
{rstudioapi}
emulation layer.To enable this feature, set
options(vsc.rstudioapi = TRUE)
in your .Rprofile.The extension provides the command
r.launchAddinPicker
which opens a filterable list of installed addins that can be launched. Bind this to a key, or access it from the command palette as R: Launch RStudio Addin
.Alternatively, individual addin functions can be bound to keys using
r.runRCommand
as described in Creating keybindings for R commands below.See the wiki for lists of supported
{rstudioapi}
commands, and verified compatible addin packages.How to disable it
For the case of basic usage, turning off
r.sessionWatcher
in VSCode settings is sufficientto disable R session watcher.For the case of advanced usage, user should, in addition, comment out or remove the
source(..)
line appended to ~/.Rprofile
.How it works
- When vscode-R is activated with session watcher enabled, it deploys the initialization script to
~/.vscode-R/init.R
. - vscode-R watches
~/.vscode-R/request.log
for requests from user R sessions. - When a new R session is created, it sources
init.R
to initialize the session watcher and writes attach request to~/.vscode-R/request.log
. - vscode-R reads the attach request and knows the working directory and session temp directory (
{tempDir}
) of the attaching session. - vscode-R watches
{tempDir}/vscode-R/globalenv.json
for global environment info and{tempDir}/vscode-R/plot.png
for plot graphics. - In the R session, the global environment info will be updated on each evaluation of top-level expression.
- When user creates or updates a plot, the
{tempDir}/vscode-R/plot.png
is updated, and vscode-R will open the plot file. - When user calls
View()
with a data frame, list, environment, or any other object, the request is written to~/.vscode-R/request.log
andvscode-R will open a WebView to show the data or open a text document to show the content of the object. - When user calls the viewer (e.g. htmlwidget, provis) or browser (e.g. shiny app, HTML help documentation), the request is written to
~/.vscode-R/request.log
and vscode-R will open a WebView to present the viewer content.
R sessions started from the workspace root folder or a subfolder will be automatically attached. The session watcher is designed to work in a wide range of scenarios:
- Official R terminal or
radian
console - R session started by vscode-R or user
- R session in a
tmux
orscreen
window - Multiple R sessions in VSCode terminal
- Multiple R sessions in
tmux
windows or panes. - Multi-root workspace in VSCode
- Switch between multiple running R sessions
- Remote Development via SSH, WSL and Docker
The status bar item shows the process id of the attached R session. Click the status bar item and it willattach to currently active session.
The R terminal used in the screenshot is radian which is cross-platform andsupports syntax highlighting, auto-completion and many other features.
Creating keybindings for R commands
There are 3 ways you can use extension functions to create keybindings that run R commands in the terminal:
r.runCommand
to make a keybinding to run any R expression.r.runCommandWithEditorPath
to create a keybinding for an R expression where the placeholder value$$
is interpolated with the current file path.runCommandWithSelectionOrWord
to create a keybinding for an R expression where$$
is interpolated with the current selection or the current word the cursor is on.
Here are some example entries from
keybindings.json
