On my machine, when I say:
# apt-cache search '^r-'
I get a list of the Debian packages of the R system. If you have disk space to waste, you could just install them all, e.g. by saying:
# apt-cache search '^r-' | awk '{print $1}' | xargs apt-get --yes install
In practice, I actually use a variant of the above, where I prune out some packages that I don't use :
apt-cache search '^r-' \
| egrep -v -i '(biology|genetic|map)' \
| egrep -v -i sql \
| awk '/^r\-/ {print $1}' \
| xargs apt-get install --yes
Once this is done, you should be able to say 'R' and get to the prompt --

At this point, you are up.
There are many beautiful CRAN packages that you'll crave. Many, but not all, are available as Debian packages. For others, you should become root, run R, and then use the install.packages command. It is simply amazing:

Warning message:
argument `lib' is missing: using /usr/local/lib/R/site-library in:
install.packages("fracdiff")
(Dunno why that warning is appearing.)
The problem with this approach is that unlike Debian packages, there is no handling of dependencies, the package database file gets wastefully downloaded every time and there is no "dist-upgrade". So use the Debian framework as much as you can, but there is actually a nice fallback.
Alternatively, wander in CRAN, bring down .tar.gz files, and say
# R CMD INSTALL file1.tar.gz file2.tar.gz ...
Return to R by example
