Error in validObject(.Object)

Biobase’s  “ExpressionSet” package:

sponge_ExpressionSet<-new("ExpressionSet",exprs=sponge_data,phenoData=pd,experimentData=experimentData,featureData=an)
Error in validObject(.Object) : 
  invalid class “ExpressionSet” object: 1: featureNames differ between assayData and featureData
invalid class “ExpressionSet” object: 2: sampleNames differ between assayData and phenoData

It is looking for the same data in all sets to match. I need to figure out how it wants featureNames and sampleNames to be specified, row headers? a column of data?
