Dear List, I realize that problems surrounding getBioC have been discussed before, but the discussion do not seem to be relevant to my question. I am running a Debian Sarge system and R 1.91 installed as a debian package. When I enter >source("http://www.bioconductor.org/getBioC.R") >getBioC() I get the error message Loading required package: reposTools Error in pkgs[, "Package"] : incorrect number of dimensions Error in getBioC(): needs reposTools to continue (various arguments to getBioC such as force=T do not help) I would be grateful for any tips! Peter
