R 4.0.2 not running on macOS 10.15.6

Good morning Marc,

Thank you kindly for your quick response.  I had read prior to installation
that I might have needed or wanted to install some different packages to
support R, but did not catch that XQuartz was a requirement.  (I also never
got prompted for various options during the installation of R-4.0.2.pkg.)

Regarding email lists, perhaps you can assist with this question: While I
don't mind becoming a registered member, I prefer not to get email traffic
from groups as I have in the past (I actually really hate email for a lot
of reasons these days), so I'm wondering, is there a way to get a digest (I
thought I saw that) of just a weekly summary of information or questions
posted, rather than getting CC:d on every back-and-forth within the user
community?  Also, do I have to become an approved user to the R mailing
list community or anything like that?  Or are all posts moderated?

Now that the weekend is upon me, I'll have some time to come up to speed on
all this.  Thanks for your patience.

Thanks again!
Mike

Greetings,

I am a brand-new user to R and want to install and run this on my iMac

running macOS 10.15.6.  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.

Yes, I read the Mac installation instructions.

Thanks in advance.

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
