[BioC] hyperG on custermized categories

[Weiwei Shi]

Hi,

Instead of using GO or KEGG categories, is it possible to use
customerized categories. For example:

CC1 : gene1, gene2, gene3
CC2 : gene4, gene5..

instead of
GO1: gene1, gene2

I am just wondering which package allows me to give my own defn. of categories.

For this purpose, I made a code from basic Hypergeometric {stats} by
using dhyper. But what I got is probability from dhyper. However, I
really need p-value instead of probability. Should I use phyper
instead?

Thanks and Merry Xmas!
