Unable to attach active R terminal: `could not find function ".vsc.attach"`

Describe the bug I updated R to the most recent version (4.2.0). As a consequence, I had to reinstall several packages, including languageserver. After this I am no longer able to attach the active R terminal to the active VS Code session. Instead, when I click the “R” button in the bottom right corner, I get the error Error in .vsc.attach() : could not find function ".vsc.attach" I tried reinstalling the R extension in VS Code as well, without any luck.

To Reproduce Steps to reproduce the behavior:

1. Upgrade R to version 4.2’
2. Install package languageserver
3. Reinstall R extension (REditorSupport)
4. Start new R terminal
5. Click on R button in the bottom left corner
6. See error

Do you want to fix by self?

If it’s just a tweak of settings, I might be able to do it myself.

setting.json (I doubt it’s related, but I can’t say for sure.)

"r.rterm.linux": "/opt/anaconda3/bin/radian",

// R command line options (i.e: --vanilla)
"r.rterm.option": [--no-save, --no-restore],

// Keeping focus when running
"r.source.focus": "editor",

// Use active terminal for all commands, rather than creating a new R terminal
"r.alwaysUseActiveTerminal": false,

// Use bracketed paste mode
"r.bracketedPaste": false,

// Enable R session watcher
"r.sessionWatcher": true,

// Delay in milliseconds before sending each line to rterm (only applies if r.bracketedPaste is false)
"r.rtermSendDelay": 8,

Expected behavior Start R kernel and and attaching to current session. R Help, plots, etc. opens in tab.

Environment (please complete the following information):

• OS: Ubuntu 20.04.4 LTS
• VSCode Version: 1.66.2
• R Version: 4.2.0
• vscode-R version: 2.4.0

Additional context In addition to reinstalling languageserver, a wide number of packages had to be updated/reinstalled. In addition, when starting a new R terminal in R, it started and Anaconda’s (much) older R version. I had to copy the R executable from /bin/R to opt/anaconda3/envs/renv/bin/R to load the newly updated R version.

@pehkawn The init.R should only be sourced in interactive sessions. I updated the wiki:

if (interactive() && Sys.getenv("RSTUDIO") == "") {
  source(file.path(Sys.getenv(if (.Platform$OS.type == "windows") "USERPROFILE" else "HOME"), ".vscode-R", "init.R"))
}

If the R session is non-interactive or is an RStudio session, then it should not source init.R.

Thanks, for the tip! Adding the following code snippet

source(file.path(Sys.getenv(
   if (.Platform$OS.type == "windows") "USERPROFILE" else "HOME"
 ), ".vscode-R", "init.R"))

at the beginning of "~/.Rprofile the solved the problem. =)
