Session watcher not attaching R and not showing plots

Hi,

Thank you so much for your work, your vscode-R package is life changing :)

I'm having issues with seeing plots (and help messages) in session watcher.

VSCode Version: 1.52.1
VSCode-R Version: v1.6.4
OS Version: Windows 10

Contents of ~/.Rprofile

# [cmr46993@login4 ~]$ cat ~/.Rprofile
Sys.setenv(TERM_PROGRAM = "vscode")
source(file.path(Sys.getenv(
  if (.Platform$OS.type == "windows") "USERPROFILE" else "HOME"),
  ".vscode-R", "init.R")
)
print("this is my rprofile")

Steps to Reproduce:

From VSCode in Windows 10, connect to linux host with Remote-SSH
Open home directory ~/
Open new terminal with VS Code
Activate conda environment where R and radian are installed
Run radian from Terminal pane (I do see my print statement 'this is my rprofile')
If I run plot(1:10, 1:10) I don't see a plot.
Click R: (not attached), I see .vsc.attach() executed in radian, but no output.
getOption('vscodeR') returns NULL
I manually copy paste my .Rprofile and nothing changes.

I can see plots if I run R: Create R terminal but I would like to use my own managed session.. any thoughts?

Here are my vscode settings:

{
    "r.alwaysUseActiveTerminal": true,
    "r.bracketedPaste": true,
    "r.sessionWatcher": true,
    "r.rterm.linux": "/home/cmr46993/.conda/envs/mygtx/bin/radian", //Use this only for Linux
    "r.rpath.linux": "/home/cmr46993/.conda/envs/mygtx/bin/R",
    // "r.rterm.windows": "/home/cmr46993/.conda/envs/mygtx/bin/radian", //Use this only for Linux
    // "r.rpath.linux": "/home/cmr46993/.conda/envs/mygtx/bin/R",
    "r.lsp.debug": true,
    "r.lsp.diagnostics": true,
    "r.rterm.option": [
    "--no-save",
    "--no-restore",
    "--r-binary=/home/cmr46993/.conda/envs/mygtx/bin/R"
    ]
}

I see that the request.log is capturing something:

[cmr46993@login4 ~]$ cat ~/.vscode-R/request.log
{"time":"2021-02-09 18:26:08","pid":26320,"wd":"/home/cmr46993","command":"attach","tempdir":"/tmp/RtmpHWXKHB","plot":"Two"}

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

No thanks, I am not very experienced :)

What's your workspace folder in vscode remote-ssh session?

What's the value of ls.str(.vsc) in your R session?

After Remote-SSH-ing into the host, I clicked to open a folder, and selected my home directory, so I believe my workspace in this case is my home directory.

r$> ls.str(.vsc)

As an alternative, I tried also right now: after Remote-SSH-ing into the host, I clicked to open a single R script, rather than a folder, but I still don't get R attached, and ls.str(.vsc) looks the same.

Hi @renkun-ken I think I've figured out the issue!!

As I said above, when I use R: Create R Terminal I am able to view plots. I noticed that the plots are saved to:
/tmp/<random_id>/vscode-R/plot.png

However, I mistakenly left out a key step in how I was trying to use session viewer, I'll rewrite it out bolding the missing step I forgot to mention I was doing:

From VSCode in Windows 10, connect to linux host login node with Remote-SSH
Open home directory ~/
Open new terminal with VS Code
Use srun to get an interactive compute node. Activate conda environment where R and radian are installed
Run radian from Terminal pane (I do see my print statement 'this is my rprofile')
If I run plot(1:10, 1:10) I don't see a plot.

The key here is that login-node/tmp/ is different from compute-node/tmp/

My remote host is an HPC, so I don't want to do heavy computational work on the login node. I want to use a compute node. I think what is happening is that r session watcher is still looking for vscode-r plots in login-node/tmp/ but my plots are actually saved to the compute-node/tmp directory.

Is there a way to change the tmp directory? For e.g., if I can put it in $HOME/tmp then I think this could solve my problem since $HOME is the same, whether I'm on a login or compute node?

EDIT: indeed, I have confirmed that r session watcher works if I don't get an interactive node :)

@radlinsky

I'm myself just getting started using SSH in VSCode.

@radlinsky As an alternative to your statements:

From VSCode in Windows 10, connect to linux host login node with Remote-SSH

and:

My remote host is an HPC, so I don't want to do heavy computational work on the login node. I want to use a compute node.

Have you considered SSH'ing directly into the compute node with VSCode? Following: https://stackoverflow.com/a/66389686
Does that make any difference?
