Could you tell me > what it means, and how I can solve the problem? I'm pretty sure this means that your R is picking up a very old version of the reposTools library. Without more information about your platform, version of R it is hard to give specific advice. You should be sure you are using R-2.0.1. One thing to try is to remove the reposTools package and try again. After removing reposTools and before running getBioC, try library(reposTools). If it tells you it can't find it, that's good. Otherwise, you have another package library on your search path (see .libPaths()). + seth
