So, what it boils down to is that I'm installing my packages at too
high of a level (I'm an administrator for my system) and should save
them in places other than the R framework folder.
The update doesn't affect any package that you installed and the GUI
remembers them (see R for Mac FAQ 5.2) - click on the search field pop-
up in Package Installer and it will offer you to select all packages
you have installed in the previous version of R.
In addition, trying to set R_LIBS via environment is a bad idea since
there are so many ways R can be started, so please use .Rprofile
or .Renviron as suggested in the documentation.

Thanks too all for the tips and links.

The standard R mechanisms for installing packages into a different

apply on Mac OS X just as anywhere else. It was not said that R
was being run from the R.app GUI, but I'll assume that is the case.
The rw-FAQ provides detailed advice for Windows users: see

The differences for Mac OS users are small -- some of the names and
how to set the library path via R_LIBS.
We arrange not to install packages within .Library on any of our
systems -- and for most users they do not have permission to do so.

This is actually an R-sig-mac question so I am responding there.
In general, if you want to install a new version without losing
the previous packages, using the finder, go to Library/Receipts
and remove the R.app and R.Gui receipts. Then install the new
version. That will keep the previous packages. This is not
mysterious, this is R.
Thanks to Simon et al. for the upgrade.

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.
