Hello, I have an ExpressionSet object (nodups) and I would like to replace its phenoData with a different data.frame object (pdata). I cannot work out how to do it. I have tired: > phenoData(nodups) <- new("AnnotatedDataFrame",pData) Error in value[[3L]](cond) : AnnotatedDataFrame 'data' is class 'standardGeneric' but should be or extend 'data.frame' AnnotatedDataFrame 'initialize' could not update varMetadata: perhaps pData and varMetadata are inconsistent? Any ideas?
