I have installed R 1.4.0 on Windows 2000 and would like to upgrade to the newest version of R. I am scared of messing this up badly and would like to know if I should: - uninstall my current version first, or - just install the newer version without uninstalling the current version Do either of these work? If both work, which is preferable? Will I have to reinstall various packages that I previously installed on 1.4.0?
When I upgrade R, y make the second option, because sometimes there are new bugs on the new version, or some of my old functions don't work on the new version for one reason or another...either way I install the new version on a different place (usually the setup installs it on a new directory rw1041) so there are independent.
That is relevant in moving from rw1031 to rw1040, say, but I don't think so for patch releases.
And later if you want to delete the old version it is very easy... Just delete the directory and the links and/or the shortcuts to the Rgui.exe program. R is a very clean program (no register stuff... )
You can also run the uninstall program in the old directory.
And yes... you must reinstall the packages, but I make a copy of the \library directory to the new one... and then I use the upgrade.package() function to get the latest pre compiled packages.
You must do that rather carefully: library contains the standard packages too, and they must be the correct versions. It is better to use a separate library for packages you install: see the rw-FAQ for how to do so. Alternatively, uninstall 1.4.0, install 1.4.1 and then copy across the rw1040\library directory. Anything packages you added will be left alone by the uninstall. However you do it, run link.html.help() afterwards.
