How to install R 2.2.0 Debian 'unstable' package in otherwise 'sarge' system

i) In general, and especially between 'testing' and 'unstable', use
apt-pinning, explained in the apt-howto packages, esp apt-howto-en for
English; and on various places across the Net; try Google'ing for
apt-pinning.

Dear Dirk,

I'll jump in because I've been wondering how to do this for some time. 

Is there any way to pin a whole series of packages using wildcards? I can 
otherwise pin r-base and r-recommended, but the packages they depend on will 
not be pinned themselves. 

It thus seems the only way to have 'unstable' R packages on my 'testing' 
system is to list them all in /etc/apt/preferences. It is neither convenient 
nor "safe" since I will eventually miss unlisted packages.

Thanks in advance!
