Could you let me know on which object I can > call se.exprs? showMethods('se.exprs') reports this correctly -- there are no (Biobase) classes on which this method is defined. Classes derived from eSet, and defined in other packages (e.g., AffyBatch, in the affy package), may have an se.exprs method. A different question is 'what methods are defined for the data I have?'
