1) Thanks to all who helped.
2) Problem is resolved, though the smoking gun hasn't been retrieved.
If anyone else encounters this problem, however, the approach I used
to arrive at a solution may be of interest
--create a new user (likely with admin rights) and verify that the
problem doesn't exist for that user (do a clean install of R and run
the code to confirm all is well)
--assuming things are good, compare contents of user/Library/
FontCollections, and consider removing "extras" in the user account
that doesn't work
--Font Finagler was suggested as a tool to clean font caches--unsure
if this is belt/suspenders/necessary or not, but just in case ...
Or, just do the work in the new user account if that suits your style,
and you don't want to take a chance on cleaning things out of the one
where things don't work.
Likely my problem arose from using setup assistant or whatever the
utility is to transfer from one mac to another, but maybe not.
Bottom line is I can proceed now with ggplot2 on the mac, finally.
