I have R and the rest of the default packages installed on Debian Linux. The biocLite script installed all other default packages (about a month ago) but failed on the genefilter install, and failed again today when i attempted to install only that package, selecting first the Washington State repository and then the Illinois repository. Here's what i got both times: > install.packages("genefilter") --- Please select a CRAN mirror for use in this session --- Loading Tcl/Tk interface ... done Warning in download.packages(unique(pkgs), destdir = tmpd, available = available, : no package 'genefilter' at the repositories > Any advice?
