I would like to know how can I obtain probenames for each row in a HTAFeatureSet@assayData$exprs object in R.

When I perform the RMA to this object I get an Expressionset with rows indicating probenames and columns indicating array names.

I would like to use this matrix but before normalizing expression data, I would like to obtain a matrix with rows indicating probenames and columns indicating array names, but with raw expression data; however, the HTAFeatureSet just indicates array names but not probenames (the rows are called 1,2,3,4....).

Thanks!
