hi Wendy,

this is an easy one, your looking for the function


defined in the GSEABase package (thus you need to load this one as well,
it gets automatically installed with GSVA).

if you're likely to be handling GeneSetCollection objects here and there
i recommend you to take a look to the Vignette "An Introduction to
GSEABase" from the GSEABase package.
