Hi,
I'm trying to preprocess Affymetrix Gene 1.0 ST array data using oligo, and
it says in the vignette to use the function getNetAffx() to retrieve NetAffx
biological annotation information.  When I try to run it, I get an error
message saying that the function can't be found.  Is there a bioconductor
package I need to install?

> featureData(genePS) <- getNetAffx(genePS, "probeset")
Error: could not find function "getNetAffx"

Thanks,
Jon
