[BioC] convert gene name to Affy ID

[J.delasHeras at ed.ac.uk]

Hi Julia,

if you check the list of annotation packages already made in the  
Bioconductor page

http://www.bioconductor.org/packages/release/BiocViews.html#___AnnotationData

you may find your array there.

I don't know if this will be your array, but just for illustration  
purposes, I see that the array "Affymetrix Drosophila Genome 2.0 Array  
annotation data (chip drosophila2)" corresponds to the package  
'drosophila2.db'
If you download and install that, and look at the user guide for that package:

http://www.bioconductor.org/packages/2.11/data/annotation/manuals/drosophila2.db/man/drosophila2.db.pdf

you should be able quite easily to match affymetrix ids to gene names,  
locations, and many other things.

I hope this helps a bit.
I have been lucky that all the arrays I have used were already  
annotated into a package :)

Jose
