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
Thanks for any suggestions. My apologies if this has been answered
before and my search missed it.

What I find simplest (on Windows at least) is
# To reinstall packages from one R version to the next:
#Currently you can do
tmp <- installed.packages()
installedpkgs <- as.vector(tmp[is.na(tmp[,"Priority"]), 1])
save(installedpkgs, file="c:/R/installed.rda")
#in the old version to get a list of packages you installed. Then in the
#new version,
load("c:/R/installed.rda")
install.packages(installedpkgs)
