Hi, Zhiyou

We have developed a bioconductor package, GeneAnswers, which also uses
hypergeometric test to run enrichment test for a group of genes. The
background algorithm is similar to GoStats/Category, but GeneAnswers can
provide keywords test and extra graphics representation for analysis.

Let me know if you have any question about it.
