(Solved) Error "Unable to determine R home: [Errno 2] No such file or directory: 'R'" while trying "from rpy2.robjects import pandas2ri" on mac

Question

I am trying to use some R packages while using python on mac. When I type in Jupyter lab

from rpy2.robjects import pandas2ri

I get this error:

Unable to determine R home: [Errno 2] No such file or directory: 'R'

     48 if lib_path is None:

Any idea how might I solve this problem?

I suppose that I have to set a variable for r_home but I dont know how can I do that. I checked these:

> system("type R")
R is /usr/local/bin/R
> R.home()
[1] "/Library/Frameworks/R.framework/Resources"
> file.path(R.home("bin"), "R")
[1] "/Library/Frameworks/R.framework/Resources/bin/R"

When I check where is R in my computer, I see:

" /Library/Frameworks/R.framework/Versions/4.2-arm64/Resources "
