Hi to all, I've installed on my pc (win xp pro os) the last version of R (1.7.1) and BioConductor 1.2.1 I'm tring to analyze a affy dataset made with hgu133a chipset. When I enter the string "xyzRMA<-rma(xyx)" it returns me this: Environment hgu133acdf is not available. This environment contains needed probe location information. We will try to download and install the hgu133acdf package. Note: No specified download type, defaulting to Win32 [1] "Attempting to download hgu133acdf from BIOCcdf/" Error in download.file(fileURL, destFile, mode = "wb", quiet = TRUE, method = method) : unsupported URL scheme I've tried also to manually download the hgu133acdf.zip and to install it in R, but it gives me this output: Error in file(file, "r") : unable to open connection In addition: Warning messages: 1: error -1 in extracting from zip file 2: cannot open file `hgu133acdf/DESCRIPTION' What can I do? Thankyou very much...

How did you try to install the .zip file? I just tried (same OS, same Rver) using 'Install from local zip file...' and it worked fine. Jim James W.
