[BioC] affy package pm ids and position on mRNA

[Rafael A. Irizarry]

i believe this information is available through the matchprobes package 
(available from 
http://www.bioconductor.org/repository/devel/package/html/index.html
)
and the hgu133a probepackage (available here: 
http://www.bioconductor.org/data/metaData.html 
)
