Hello, I am running library (affy) under UNIX. As usual, I have to put the libraries under my ~home directory called .Rlib. When the program trying to automatically download the CDF packages, it generates an error. > data<- ReadAffy() > data Environment mgu74av2cdf is not available. This environment contains needed probe location information. We will try to download and install the mgu74av2cdf package. Note: No specified download type, defaulting to Source [1] "Attempting to download mgu74av2cdf from BIOCcdf/" Error in download.file(fileURL, destFile, mode = "wb", quiet = TRUE, method = method) : unsupported URL scheme Error in inherits(cdf.env, "try-error") : Object "cdf.env" not found Any fix of this problem? Can I use getBioC() to get the CDFs? Write now, I am manually use R INSTALL for the CDFs. Any alternatives insider R? Thanks! Simon

The pages 3 and 4 of the vignette "affy: Automatic downloading of cdfenvs" deals with the issue. Try 'openVignette()' in your R session and spot it in the list. Hopin' it helps, L.
