Painless way to install a new version of R? - Stack Overflow

"My preferred method on Windows (upgrading 2.10.1 to 2.11.0):

• Install R-2.11.0

• Copy R-2.10.0/library/* to R-2.11.0/library/
  

• Answer "no" to the prompts asking you if it is okay to overwrite.
  

• Start R 2.11.0 and then type
  

• update.packages()"
