Could this be related to the administrative rights of the user?
If a user had administrative rights, packages would be installed
into the /Library/Frameworks directory, and then updating (to, I
think a new major version) would remove them. Without the
administrative rights it would install the packages in your home
directory, where the R_LIBS environmental variable would always
point to the same place.

The title says it all. Does anyone know of a way to save your packages
when you upgrade to a new version of R? This may seem petty, but I'm
accumulating enough packages that having to download and install each of
them anew every time I install a new version of R is rather of a pain.
Ideally, I would like the new version of R to recognize the packages I've
installed on the previous version without needing to reinstall the
packages. Is that possible?
My system: Mac OS 10.5.4.
Current R version: 2.7.1
Mac OS moves in mysterious ways, but apparently your installation moves in
more mysterious
ways than most.
I also (by necessity, not by choice) run Mac OS. But I certainly don't
lose my
packages when I update R. The new version of R certainly ``recognizes''
the packages
that I have installed. No action required.
There may be something funny about *where* you have your packages
installed, and
what environment variables you have set.
To answer your question ``Is that possible?'' --- Yes. Not just possible,
but universal. Except, it would seem, in your case. What have you done
to offend the gods? :-)
Actually have had the same problem as James. By default, unless I'm
mistaken, R will save installed packages within the "R.framework" framework
(system-wide installation). This framework gets completely replaced when a
new version is installed. In my system, the location of these packages is:
/Library/Frameworks/R.framework/Resources/library
So unless I am mistaken you have to take some action to prevent packages
from being installed there. I do hope I am wrong.
I'm not sure --- I find Mac OS very confusing. But I have the
***impression*** that
(on my system) by default packages get installed into
~/Library/R/2.7/library
i.e. into a library inside the directory tree rooted in my login
directory.
I don't use this --- I've created my own library ~/Rlib and have
set up an environment variable to point to it.
(This works properly only if you start R from the command line; for
reasons I don't understand if you start R by clicking on the icon
then R doesn't know about the R_LIBS environment variable. But since
all civilized people start R from the command line .....)
I have no idea why youse guys' systems would eschew using
~/Library/<whatever>.
cheers,
