[BioC] Gene Mapping on Chrosmosomes

[Robert Gentleman]

It is pretty simple,
find the annotation package for your chip (your name is not right 
though, I think) and there is a CHRLOC table in it, with chromosome 
locations. You only need to do more if you want to make use of the 
plotting functions (in geneplotter, for example)

Robert

eg
  library(hgu95av2)
   ?hgu95av2CHRLOC

should get you started - and as others have said, the vignettes should 
give you lots of information, but let us know if they are not clear
(or our new book)
