Hi,
I'm running into some MacOS - Sequoia problems with XQuartz, and it
occurred to me to ask whether it's actually needed for successful
completion of the command

That command at some point causes XQuartz to launch -- at least on my
system -- so now I'm wondering if that is normal?
It depends on the package. Most packages won't need XQuartz. You could
configure R to use it as a default graphics device by setting
`options(device=X11)` but normally most packages don't use it. Your
startup script might do that though.
Some packages do use it. If the package calls X11(), that will open
XQuartz. If it uses the rgl package, it will default to opening
XQuartz, but can be told not to.
I don't know of other examples, but I wouldn't be surprised if there are
some.
