[BioC] Hello,I have very urgent questions

[Saroj K Mohapatra]

Dear Wei:

The message indicates some problem with memory. You need a machine with 
more memory. You might also try with smaller data (e.g., fewer 
microarrays, etc.) and see if the problem persists.

There are functions that get the Gene Ontology annotation for genes in 
the org.xx.eg.db packages, where xx refers to the short form of the 
species names (Mm for Mus musculus, Hs for Homo sapiens, etc). Once you 
load the library, you could use the function org.Mm.egGO  to map between 
Entrez Gene IDs and Gene Ontology.

If you provide a reproducible example, it would be easier for others to 
understand your situation and send more helpful comments.

Best wishes,

Saroj

I have asked some people, but they only know how to get the Gene Ontology of single gene, but in my data I have thousands of genes.  Would you kind to  tell me the R commands to get the Gene Ontology file of a list of genes?
