R help - Sep 2011 - Update packages problem

R-help, I recently updated R from 2.13.0 to 2.13.1 (32-bit Windows version) and
now have a problem updating packages.  I am running Windows 7 as operating
system.  As the FAQ suggests, I uninstalled 2.13.0 before installing 2.13.1.  On
first opening R, I ran "update.packages(checkBuilt=TRUE, ask=FALSE) ras
also recommended and selected the NS Cran mirror.  On doing this the following
error messages occurs: update.packages(checkBuilt=TRUE, ask=FALSE)
--- Please select a CRAN mirror for use in this session ---
Warning in install.packages(update[instlib == l, "Package"], l,
contriburl = contriburl,  :
  'lib = "C:/Program Files/R/R-2.13.1/library"' is not
writable
Error in install.packages(update[instlib == l, "Package"], l,
contriburl = contriburl,  :
  unable to install packages   Any suggestions as to how to correct this problem
would be appreciated.  Thanks. Regards,Deelman

Perhaps not necessary for an update from 2.13.0 to 2.13.1

Windows is protecting you. You need to convince it you do not need  
protection. Search for ways to increase your Win-fu.
