Hi Micha, Thanks for the reply. I ran the script lines you sent both in the terminal as well as a GRASS session. Rscript is recognized in the terminal command but not in the GRASS 8.0 command. Since GRASS 8.0 did not recognize Rscript I tried making a symbolic link for "Rscript" to the full path: /usr/local/bin/Rscript. This still doesn't recognize the command and I'm unsure how else to work around it.
Any Mac aficionados reading this - do you have an idea to resolve this?
