HI edgeR users,


I identified differential expressed genes (DEGs) using the edgeR and then did gene ontology analysis for top 100 DEGs. I got the following results. the first GO term is the immune system process, there are 42 of my top 100 genes are in this immune related process.  how do I retrieve the list of those 42 entrez id since my input vector is 100 entriez gene ID?


Thank you,

You could look at the mapping objects in The org.Hs.egGO might be a useful.
