I successfully downloaded the correct package, installed it with no problems (I was not given any options for Tcl/Tk or Texinfo), and started it up as any other normal app.  Some introductory commands like license() and help() worked just fine.  But when I went to execute demo(), it just beach-balled.  I’ve had to force-quit R a number of times.

Hi,

Sounds like you need to install XQuartz:

  https://www.xquartz.org

which is referenced in the macOS installation instructions and the macOS specific FAQ.

Also, be aware that there is a macOS specific e-mail list here:

  https://stat.ethz.ch/mailman/listinfo/r-sig-mac

which is where macOS specific R issues should be posted.

You will need to re-install XQuartz any time you upgrade/install a new version of R.

Regards,

Marc Schwartz
