Windows: updating to R 1.2.2

Forgive me, but while I find the documentation for initially installing R to be clear, I'm not so happy about updating. I want to update from R 1.2.1 to R 1.2.2 (mainly so I can get the debugged version of pictex() ). Now I have downloaded the base zip files, say to Z:\Program Files and my existing installation of R 1.2.1 is sitting in Z:\Program Files\rw1021. Running rwinst.exe I need to nominate an Install directory. I can nominate a new directory Z:\Program Files\rw1022, but then I will not be able to access my packages already installed for R 1.2.1. I can nominate Z:\Program Files\rw1021 to install over the top of the old version, but I am scared that this might stuff everything up, and I will have no working version of R. I am just looking for some reassurance that the second course of action is safe, or alternatively to be told the bad news that I must re-install all of my existing packages under the new version of R.
Two ways: - set .lib.loc also to the library path of the "old" version of R, e.g.: .lib.loc <- c(.lib.loc, "c:/whateverdirectory/library") - copy the libraries from the library-dir of the old version into the library-dir of the new version Suggestion: For additionally libraries make an independent directory, say "c:/program files/R-libs" for example. Install all new libraries into this directory and set .lib.loc as needed. So updating R is not so much work in the future.
