Yes, these are the correct packages, and you can see when they were updated by: source("http://www.bioconductor.org/biocLite.R") biocLite(c("porcinecdf","porcineprobe")) packageDescription("porcinecdf") packageDescription("porcineprobe") > > In my script I have included annotation of the final results using > for example hgu133plus2 - Affymetrix Human Genome U133 Plus 2.0 Array > Annotation Data (hgu133plus2) for Human 133 plus 2 arrays from > Affymetrix.

No, the porcine package has not been made. You will need to use the AnnBuilder package to build your own. For tips, I would search the list archives. This is one of the most common questions, so a search with reasonable terms should turn up lots of good information.
