Updating R-Software without complete new installation

There is a danger that some package that you depend on may not be immediately available with the new version of R. It is safer to install the new version in parallel with the old and then if it does not work you can revert to the old. For Windows follow the recommendations in the FAQ but do not delete the library directory until you are sure that every thing works. If you must uninstall your old version keep a copy of your old library directory. You can then download and reinstall the old version and use your old library directory. John Frain

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.
I usually just install the new version over the old one (to the same folder), then update.packages(ask=FALSE) This particular upgrade required update.packages(checkBuilt=TRUE,ask=FALSE) I do this way since R version 1.6 (or even 1.4), and everything works fine and smooth. Sometimes I have to manually delete older README's or something like this. -- View this message in context: http://www.nabble.com/Updating-R-Software-without-complete-new-installation-tf4632860.html#a13230136 Sent from the R help mailing list archive at Nabble.com.
