[BioC] Mapping Affy probes to OperonID or ensemblID

[Julian Lee]

Hi all,

I'm relatively new to R/Bioconductor.

I'm trying to map Affy's HGU133plus2 probesids with OperonID/EnsemblIDs

Eg. 
OperonIDs
H200007039

EnsemblIDs
ENSG00000169678

Desc
Linker for activation of T cells (36 kDa phospho-tyrosine adaptor protein) (pp36) (p36-38).

DB website link
http://omad.operon.com/human2/index.php

Is there an environment for OperonIDs in the hgu133plus2 package? 
Eg.
library(hgu133plus2)
xx<-as.list(hgu133plus2OPERONID)
myU133plus2probes<-xx[match(operonidsofinterest,xx)]

If there isn't, could we build one? 

Thank You

regards
