Dear Sir: Thank you for this R tool. As I sometimes have a developer role, I though I would give you some feedback. I recently installed BioConductor using source("http://www.bioconductor.org/getBioC.R") and getBioC(libName = "all"). Although I was suscessful in completing the vignette, "HowTo: Automated Querying of PubMed Data", I spent quite a bit of time on the step "library(hgu95a)" First I got the no package error, so I tried hgu95av2 with the same result. Next I tried getBioC(libName = "hgu95av2") and got the error that the library is not valid. Finally I download the tar.gz file to my disk and installed it using the R command. I guess that hgu95a is no longer available, and probably its absence affects only tens of genes.
