vscode could not open radian (Linux, Manjaro)

Question

Open a R script and click Run Source then I get

The terminal process "/home/xxx/miniconda3/bin/radiant ''" failed to launch (exit code: 1).

and a massage in terminal window

Traceback (most recent call last)
  File "home/xxx/miniconda3/bin/radian", line 8, in <module>
    sys. exit(main())
  File "home/xxx/miniconda3/lib/python.7/site-packages/radian/init.py", line 44, in main
    r_home = Rhome()
  FIle "home/xxx/miniconda3/lib/python.7/site-packages/rchitect/utils.py", line 84, in Rhome
    raise RuntimeError ("Cannot determine R HOME.")
RuntimeError: Cannot determine R HOME.

But, in system terminal I can use radiant and find R HOME.

I have tried reinstall vscode and all extentions, it doesn't work.

And after I read massage in terminal and read code in ~/miniconda3/lib/python3.7/site-packages/rchitect/utils.py

I add

export R_HOME="/home/xxx/miniconda3/bin/R"

in my .zshrc. But it doesn't work.

And in my environment value there is only one value

RSTUDIO_WHICH_R=/home/xxx/miniconda3/bin/R

Thanks for @randy3k help.

Across to read github page, I find a way to solve it.

I add a option in my vscode settings.

  "r.rterm.option": ["--r-binary=/home/xxx/miniconda3/bin/R"],
