 I think we are using different terminology. By 'gene ID' I am referring 
 to Entrez Gene IDs which are the numeric identifiers you are seeing. You 
 can use the org.Hs.eg.db package to map those identifiers to others if 
 you want. Perhaps you would prefer gene symbols, in which case:

 library(annotate)
 library(org.Hs.eg.db)
 rownames(summ) = getSYMBOL(rownames(summ),"org.Hs.eg.db")

 Will replace the numeric IDs from the summ matrix with gene symbols 
 instead.
