I think your only option is run R in the cloud using Posit Cloud. Let me know if that works for. you!

I have version 3.3.2 on my Mac from an earlier attempt of using R. Will it overwrite if I install the latest release? Or should I try to deinstall the older version first? And what package should I download? I have an iMac from 2015 with macOS Monterey Version 12.6.8

Yes, your packages will be overwritten if you install a newer version of R. However, 3.3.2 is very old at this point so I'd definitely recommend it. No need to uninstall anything first. In terms of packages, I'll give you a few to install in future lessons. Other than that, up to your needs!
