[R] Updating R-Software without complete new installation

[Schmitt, Corinna]

Hallo,

as I see there is a new version for R available. Can anyone tell me how
I can update my version 2.5.0 under Windows? The last times I just
uninstalled the old version and installed the new one. Afterwards I had
to install also all needed packages again. All in all it cost me half a
day until my system works fine again. Is there a quicker option? If yes
please tell me the commands.

Thanks, Corinna
