[BioC] A question about org.Hs.egMAPCOUNTS

[Gilbert Feng]

Hello, BioC forks,

I notice that org.Hs.egMAPCOUNTS reports that org.Hs.egGO2EG is 8245. Are
these 8245 genes are unique or, do all of GO terms contain 8245 human genes
(could be counted many times)? Actually, I wonder how many unique human
genes in GO and its subdirectories, BP, MF and CC. Is there any function to
retrieve such information easily or I have to write several lines to do
that?

Thanks a lot!

Gilbert
