[R] R-update - what about packages and ESS?

[Prof Brian Ripley]

Without knowing your OS this is hard to answer (and is the wrong list for 
the ESS question).

For Windows users, the packages part is covered in the rw-FAQ.

For Unix-alikes, it all depends how the update was done, but normal 
package update mechanisms (such as RPM) will not wipe out previously 
installed R packages: nor will 'make install'.

In either case you don't need root access to install packages, as you can 
use a private library.  We have things set up so a user's R_LIBS is 
something like

	R_LIBS=~/Rlibrary:/usr/local/Rlibs:/usr/local/BioC

and then install.packages() automatically installs into the user's own 
library (if it has been created).
