A word of warning. 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.
