3. Install the R Zed extension through Zed's extensions manager.

For example on macOS:

Rscript --version
Rscript -e 'options(repos = "https://cran.rstudio.com/"); install.packages("languageserver")'
Rscript -e 'options(repos = "https://cran.rstudio.com/"); install.packages("lintr")'
Rscript -e 'packageVersion("languageserver")'
Rscript -e 'packageVersion("lintr")'

Ark Installation

To use the Zed REPL with R you need to install Ark, an R Kernel for Jupyter applications. You can down the latest version from the Ark GitHub Releases and then extract the ark binary to a directory in your PATH.

For example to install the latest non-debug build:

# macOS
cd /tmp
curl -L -o ark-latest-darwin.zip \
    $(curl -s "https://api.github.com/repos/posit-dev/ark/releases/latest" | \
    jq -r '.assets[] | select(.name | contains("darwin-universal") and (contains("debug") | not)) | .browser_download_url')
unzip ark-latest-darwin.zip ark
sudo mv /tmp/ark /usr/local/bin/

# Linux X86_64
cd /tmp
curl -L -o ark-latest-linux.zip \
    $(curl -s "https://api.github.com/repos/posit-dev/ark/releases/latest" \
        | jq -r '.assets[] | select(.name | contains("linux-x64") and (contains("debug") | not)) | .browser_download_url'
    )
unzip ark-latest-linux.zip ark
sudo mv /tmp/ark /usr/local/bin/
