Hi,
I try to execute the seven lines of code below to plot a graph. But I
am failing as the messages below show. Where am I going wrong?

So It appears that X11, a.k.a. XQuartz on a Mac, is failing to load. You
probably need to reinstall XQuartz with a current version that matches
your version of R. You are also getting a message saying Java sdk cannot
be found.
You also appear to be attempting to load the version for R 4.1 while the
current version of R is 4.2. The R "ecosystem" needs consistency in
versions of R, XQuartz, Java, and R packages. You will probably get
better success if you first upgrade R, then reinstall XQuartz, then
reinstall or update Java, and finally update all your installed packages
including rgl and then give it another go.
Finally, this is Rhelp. There is a SIG for R-Mac users. This question
would have been more on-topic for that help mailing list.
