Installation: macOS

1. vscode-R

Install vscode-R in VSCode by searching ikuyadeu.r in extension market place.

If the R installation is from CRAN, then the default settings should work out of the box. Otherwise, you may have to change r.rterm.mac to the path to your R executable, which will be executed on command Create R Terminal.

If you are interested in the experimental features provided by R session watcher, you may enable it in the VSCode settings:

{
  "r.sessionWatcher": true
}

2. languageserver

languageserver is an implementation of the Language Server Protocol for R.

Run the following commands in R.

You may install the latest stable release from CRAN:

install.packages("languageserver")

or install the development version with newest features:

remotes::install_github("REditorSupport/languageserver")

3. vscode-r-lsp

Install vscode-r-lsp in VSCode by searching reditorsupport.r-lsp in extension market place.

If the R installation is from CRAN, then the default settings should work out of the box. Otherwise, you may have to change r.lsp.path to the path to your R executable, which will be executed to start the R Language Server as a background process.

4. radian

radian is highly recommended as the R terminal for interactive use. It requires python which should be available on macOS out of the box.

pip install -U radian

You may run which radian to see where your radian executable is located (typically, /usr/local/bin/radian).

Then the following VSCode settings should be updated to properly use radian as the default terminal.

{
  "r.bracketedPaste": true,
  "r.rterm.mac": "/usr/local/bin/radian"
}
