I have the entrez IDs of a set of genes and I test these with a universe of entrez IDs in hyperGTest to get the significant KEGG and PFAM terms.

How can I get this? I guess GOstats is using a mapping of sorts in the hyperGTest, but where can I find it? >> >> > > Look at the org.Hs.eg.db package (for human).

You can also find this information inside of the chip based annotation packages. Marc
