R terminal not starting - "radian not found" error

[BittuChan]

Hi everyone,
Just installed the R extension in VS Code, but when I try to run R code, I get:
radian not found. Please check your r.rterm.windows setting.

I have R 4.3.2 installed and it works fine in RStudio. I'm on Windows 11 and R is in C:\Program Files\R\R-4.3.2\bin\x64\R.exe.

Do I need to install radian separately, or should the extension use the default R terminal?

The extension defaults to looking for radian (an enhanced R terminal), but you don't need it. Just point the extension to your R executable.
Add this to your VS Code settings.json:
"r.rterm.windows": "C:\\Program Files\\R\\R-4.3.2\\bin\\x64\\R.exe"

Or if you want to use radian (it's better tbh), install it via pip:
pip install radian
Then set:
"r.rterm.windows": "radian.exe"

Also make sure Python and pip are in your PATH if you go the radian route.

@Shiven0504 thanks for your suggestion, I just pointed it to the R.exe path and it's working now. Might try radian later, but the default terminal is fine for what I need. Appreciate the quick fix 🙏
