Help with 'annotation' in GOHyperGParamsClass

Dear cateGOry experts,
hyperGTest documentation states that YEAST cannot be used as 'annotation'
when evaluating gene ontology representation status for a given set of
'geneIds'.

Because I am using a custom print I believe I need to create my own data
package to use as the annotation file for 'annotation'.  Can someone please
describe how to make a data package that will be compatible with the
'annotation' required for proper function of hyperGTest?

Session Info below,

Thanks,

Jason
