"Validation: Get classification performance AND costs"

Hi!  I'm a RapidMiner newbie and I love the tool.  I have a number of questions, but I'll limit this post to the one.

I'm trying to validate a cost sensitive classification method that I implemented.  I would like to produce both a confusion matrix and misclassification costs based on applying the generated model to a test training set.  Right now, I can only seem to produce one or the other by having either as the last step in an operator chain.  Am I missing an easy way to produce both or do I need to implement my own operator that does this?

Any help is appreciated.

    Hello Michael

    Do you know the IOMultiplier - Operator?  Applying this to the test-set allows you to perform both PerformanceOperators in a row.

    hope this what you need
