`.vsc.attach()` not found for self-managed R sessions in tmux

Describe the bug When working in a Remote SSH environment, .vsc commands are not found for R sessions created manually within tmux, even after following the instructions found here. They work fine when creating an R terminal using the control palette command.

Details that may be relevant:

• renv version 0.13.2 (.Rprofile has been modified as per these instructions at ~/.Rprofile as well as within the renv project)
• using radian R console

To Reproduce Steps to reproduce the behavior:

1. From VS code, connect to SSH host using Remote SSH extension
2. Create a new terminal
3. Start tmux
4. Within tmux, start a radian console
5. Within radian, try running .vsc commands or View(), plot(), etc.

Do you want to fix by self? (We hope your help!)

(If related)setting.json

// R path for Linux
"r.rterm.linux": "r4", // alias for 'radian --r-binary=/opt/R/4.0.2/bin/R'

// R command line options (i.e: --vanilla)
"r.rterm.option": ["--r-binary=/opt/R/4.0.2/bin/R"],

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

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

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

// 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

• when running .vsc.attach(), the R console should be attached to the session watcher
• when running View() and plot() commands, the associated viewer/plot object should be displayed in a panel

It appears that the .Rprofile must contain a trailing new line (see here), which may have been removed by VS code linters. After adding a new line, everything works as intended.

It seems that the init.R contains the expression now, so we don’t need to set that in our Rprofiles. https://github.com/REditorSupport/vscode-R/blob/8ec924b2a1b18ea722172995fa702c938604ecaf/R/init.R#L9-L17
