1. Prerequisites

2. R extension Settings:

Update R terminal settings:

Define R path:

Update the path directly in the R extension settings. Make sure you are editing the settings for your remote VSCode instance, as shown at the top of the screenshot:

Alternatively, update the .vscode/settings.json file:

{
    "r.rterm.linux": "/path/to/R",
    "r.lsp.path": "/path/to/R"
}

3. Link Your .Rprofile:

Add the following lines to .Rprofile:

Sys.setenv(TERM_PROGRAM = "vscode")
source("/path/to/your/.vscode-R/init.R")

4. Activate your Conda environment and start R::

conda activate r_env
R

Optional 5. Attach VSCode to R Session:

.vsc.attach()

6.Tips

** Use tmux for Persistent Sessions: **

1. Create a new tmux session:

   tmux new -s r_session

2. List all sessions:

   tmux ls

3. Reattach to a session:

   tmux attach -t r_session
