Hi,

 I am not having any prior experience in using R/Biocunductor software, can any one please help me in writing a function that takes a list of entrez gene identifiers as an input (e.g. differentially expressed genes in a gene expression study) and a list  of background genes (e.g. entrez gene identifiers of all probed genes on the microarray) and performs a hypergeometric test for over representation against GO and KEGG. 

Regards,
Pradee.
