Guys, guys, Can't believe this. Could get even passed the installation! There seemed to be a function missing in the new reposTools library which is needed for install BioC. This shouldn't be possible. Installation script should really not fail.... This function: getRversion <- function() { return(buildVersionNumber(strsplit(R.version.string,"( )|(,)")[[1]][3])) } I copied from 1.4.3 and copied it into .../R/versNums.R of version 1.4.11 Beeewww.... took me 2 hours to solve this bug.

It is if you use the proper version of R. > I copied from 1.4.3 and copied it into .../R/versNums.R of version 1.4.11 > Beeewww.... took me 2 hours to solve this bug. But it isn't a bug. As per your previous message, you were using R-1.9.1 and using 'devel=T'. If you followed the instructions properly, you would be using R-devel (which is currently R-2.0.0. Alpha), in which you'll find that the 'getRVersion' function is now part of R and not in reposTools, thus the removal of said function from reposTools. Furthermore, if you followed the instructions properly and used the release version of BioC packages with your R-1.9.1, you wouldn't have found this "bug". -J
