Thanks Dirk! The prior install and updates had been running fine for so
long I forgot all about the documentation on Renviron, Startup, etc.!
Thanks. Will changing the libPaths in Renviron.site help with the issue
that the operating system doesn't seem to recognize the installation re:
message that the "software is not installed" when I tried to remove it?
Also what does it mean in your note when you say: "you will need to
trace want on your box does"?
Thanks!

What you had (and what you want, if I read the message correctly) is an
explicit setting for (e.g.) .libPaths() which I like, but which I can't
"enforce" in the package -- I once tried about 1 1/2 years ago and all broke
loose because those who had ~/R/... path no longer saw it.
So now again, and as it had been since the 2000s, this is governed by a
setting in eg
/etc/R/Renviron.site
which is a convenience symbolic link to
/usr/lib/R/etc/Renviron.site
The file has comments, so see those. My (personal) version just comments the
settings out so that I get
R> .libPaths()
[1] "/usr/local/lib/R/site-library" "/usr/lib/R/site-library"
"/usr/lib/R/library"
R>
Now, the tricky bit that R allows half a dozen ways to influence this -- see
help(Startup) in R for all the gory details. So I fiddling with
Renviron.site does not influence a fresh R session you will need to trace
want on your box does -- "dotfiles" can be sourced from the current
directory, the home directory, the /etc/ directory, ... and environment
variables enter too.
Keep us posted, hope this gets you started.
