R help - Apr 2010 - How do you change library location ? (in R under windows XP)

Due to the new R 2.11 release, I want to implement Dirk's suggestion
here<http://stackoverflow.com/questions/1401904/painless-way-to-install-a-new-version-of-r>
.

So for that I am asking - How can I (permanently) change R's library path?
(The best solution would be one that can be run from within R)
Thanks,
Tal

Permanently? Not sure, but in .Rprofile you could leave code that sets  
with .libPaths()

 > .libPaths()  # will accept alterations
[1] "/Library/Frameworks/R.framework/Resources/library"

To me, it seemed more straightforward to do this outside R.  

Just set the environment variable R_LIBS in Windows to something like

R_LIBS=c:/R/Library

Then, delete your R installation. Install the new version and all
desired packages.  The add-on packages will be located according to
your environment setting, and future updates will not require add-on
packages to be copied or reloaded.
