[BioC] Using ChromHeatMap with the org.Mm.eg library

[Michael Muratet]

Greetings

I am attempting to make a ChromHeatMap from RNA-seq data with Entrez  
IDs using org.Mm.eg for annotation. The original data was aligned to  
the UCSC knownGenes table and I can map the original identifiers to  
just about any other system using the browser tables. I tried

 > chrData <- makeChrStrandData(matrix(neuro.ca.7d), lib="org.Mm.eg")
Error in makeChrStrandData(matrix(neuro.ca.7d), lib = "org.Mm.eg") :
   Error: Data matrix must have row names corresponding to probe IDs.

I suspect that I'm missing a step somewhere but I can't find it in the  
documentation. Is there a way to get the annotation from the org.Mm.eg  
data?

Thanks

Mike
