Documentation amendment suggestion

I am an RStudio user wanting to experiment with using radian (probably within Code).

I installed miniconda3 (python 3.9) on Windows 10, and then installed radian without error. Then when I typed radian at the anaconda prompt, I got:

Traceback (most recent call last):
File "C:\Users\Francis\Programs\miniconda3\Scripts\radian-script.py", line 9, in
sys.exit(main())
File "C:\Users\Francis\Programs\miniconda3\lib\site-packages\radian_init_.py", line 51, in main
r_home = Rhome()
File "C:\Users\Francis\Programs\miniconda3\lib\site-packages\rchitect\utils.py", line 85, in Rhome
raise RuntimeError("Cannot determine R HOME.")
RuntimeError: Cannot determine R HOME.

I then tried following the instructions to set R HOME in your README, like this:

env R_HOME=C:\Users\Francis\Programs\R\R-4.1.1 radian

but this gave the error:

'env' is not recognized as an internal or external command,
operable program or batch file.

However when I did

set R_HOME=C:\Users\Francis\Programs\R\R-4.1.1

I got no error and was able to then start radian.

I think it might be helpful to others to include the set option as well as the env option in the README.

I also got the same issue:
I had installed R
I proceeded to add the R installation to the path to the system environment variables, this allowed me to run radian without issues.
