Converting label from pseudo polynomial to binomial ??

Hi everybody,

I have a data set with polynomial labels.
I use ExampleFilter to remove examples from the data set so that effectively only examples from two classes remain.
But RapidMiner still thinks that the data are polynomial and not binomial and I'm now looking for an operator to fix this.
Is Nominal2Binomial the correct way?  It creates new attributes which is not really what I want...

Thanks,

Axel

    Okay, I found a solution !

    AttributeSubsetPreprocessing        => Isolate my label attribute
      Nominal2Binominal                         
      AttributeFilter                                => Remove unwanted attributes generated by Nominal2binominal
    ChangeAttributeRole                      => Recreate label type

    after all, not that difficult  :-)
