Yes, #66 is basically what you want, multiple user libraries for the same R version. We'll have that soon.

I have only started using it but works perfectly so far (I like the menu bar app as well) 🎉! Thanks for working on this so quickly.

Unfortunately it is not that simple, because all shared libraries are hard-wired to link to the original installation:
❯ otool -L /Library/Frameworks/R.framework/Versions/4.1/Resources/library/stats/libs/stats.so
/Library/Frameworks/R.framework/Versions/4.1/Resources/library/stats/libs/stats.so:
stats.so (compatibility version 0.0.0, current version 0.0.0)
/Library/Frameworks/R.framework/Versions/4.1/Resources/lib/libRlapack.dylib (compatibility version 4.1.0, current version 4.1.3)
/Library/Frameworks/R.framework/Versions/4.1/Resources/lib/libRblas.dylib (compatibility version 0.0.0, current version 0.0.0)
/Library/Frameworks/R.framework/Versions/4.1/Resources/lib/libgfortran.5.dylib (compatibility version 6.0.0, current version 6.0.0)
/Library/Frameworks/R.framework/Versions/4.1/Resources/lib/libquadmath.0.dylib (compatibility version 1.0.0, current version 1.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1281.0.0)
/Library/Frameworks/R.framework/Versions/4.1/Resources/lib/libR.dylib (compatibility version 4.1.0, current version 4.1.3)
/System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 1673.126.0)
This is even true for non-base CRAN packages:
❯ R-4.1 -q -e '.libPaths()[1]'
> .libPaths()[1]
[1] "/Users/gaborcsardi/Library/R/x86_64/4.1/library"
❯ otool -L /Users/gaborcsardi/Library/R/x86_64/4.1/library/filelock/libs/filelock.so
/Users/gaborcsardi/Library/R/x86_64/4.1/library/filelock/libs/filelock.so:
filelock.so (compatibility version 0.0.0, current version 0.0.0)
/Library/Frameworks/R.framework/Versions/4.1/Resources/lib/libR.dylib (compatibility version 4.1.0, current version 4.1.2)
/System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 1853.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1311.0.0)
So you would need to modify these paths using install_name_tool for every shared lib in base R, and then also after every single package installation.
OTOH, you don't need two separate R installations if the only difference is in the user package libraries. You can modify R_LIBS_USER in .Renviron to switch between two user libraries.

Thanks, I would not have worked that out! I know that you can use .Renviron but I have found that to be more work in the past, particularly when using RStudio. I had a similar setup with two R installations that worked fine with the rswitch tool. I was hoping to be able to do the same thing here but maybe the extra things you have built around the installation make that impossible and I should just go back to what I had before.

FYI: the pre-release at https://github.com/r-lib/rig/releases/tag/v0.3.1pre now supports multiple libraries and switching between them. This is currently an experimental feature and it might change in the future. Feedback is welcome.

I am going to close this now. If we need more features related to this we'll create new issues.
