I just have a problem when I do cluster analysis following Bioconductor basics tutorial. The problem happened here:
 
> X <- scale(X)
> golubTrainSub <- golubTrain[good, ]
> slot(golubTrainSub, "exprs") <- X
 Error in checkSlotAssignment(object, name, value) : 
   "exprs" is not a slot in class "ExpressionSet"
 
Can anybody tell me how to do it? I used new version of golubEsets
(Golub_Train).

Thank you very much.TH
