[BioC] Creating annotation database for GOstat

[naomi at stat.psu.edu]

I have a data base with gene names and GO annotation for maize.  Having
selected a gene list, I want to get this annotation file into R in a
format that allows me to run GOstat.  I am not sure how to proceed.  A
sample of the annotation file is below.

GRMZM2G026396,,
GRMZM2G160606,5737,cytoplasm
GRMZM2G103702,,
GRMZM5G810061,3924,GTPase activity
GRMZM5G810061,5525,GTP binding
GRMZM2G019356,,
GRMZM2G032655,,
GRMZM2G098423,51287,NAD binding
GRMZM2G136395,,
GRMZM2G137676,30599,pectinesterase activity
GRMZM2G137676,42545,cell wall modification
GRMZM2G137676,5618,cell wall

Thanks for any assistance.  A pointer to the correct vignette or manual
should be enough.
