What do you mean by terms?  Does the summary method on the test result
do what you want?  Try:

    ans <- hyperGTest(yourParams)
    summary(ans)

Perhaps you want:

   library("GO")
   someGOTerms <- mget(someGOIDs, GOTERM)

Have you had a look at the vignette that comes with GOstats?  Try:

   library("GOstats")
   openVignette(package="GOstats")
