I’m trying to follow the install instructions for CmdStanR and the first step fails:
> install.packages("devtools") Warning in install.packages("devtools") : 'lib = "/Library/Frameworks/R.framework/Versions/3.5/Resources/library"' is not writable Would you like to use a personal library instead? (yes/No/cancel)
I just migrated from my old Macbook to a new Macbook with upgraded OS. My system reports Catalina 10.15.2.
RStan still works.
Any suggestions as to how I should proceed?
