Hi, Thanks very much to all Bioconductor developers for version 1.2! Often I can't remember the capitalization in Bioconductor package names, so after running getBioC() to get Bioconductor 1.2, I accidentally typed: library(BioBase) instead of library(Biobase). This is obviously Operating System dependent, but in Windows 2000, R 1.7.0, getPkgVigs and .First.lib gave some rather unfriendly errors, e.g. "packages: Biobase are not installed" : Perhaps one way to get around this is to change the following line in Biobase's getPkgVigs : rows <- match(package, pkgs) to : rows <- match(tolower(package),tolower(pkgs)) Regards, James > library(BioBase) Welcome to Bioconductor Vignettes contain introductory material.

I realize that sometimes capitalization schemes can be difficult to keep track of, but the only reason you can load the package at all that way is that you're using an OS that has a poor notion of case dependency. -J
