help("update.packages") 

	will tell you about loc.lib that can restrict 'where to look'.		

Also, if you do 'sudo apt-get install littler' you will find a script
update.r in the examples/ directory that does just that -- updating of
packages only in /usr/local/lib/R/site-library/

There is 'R CMD remove' but I just rm -rf, albeit carefully :)

Cheers, Dirk
