Hi, I'm new to RapidMiner, so perhaps this is a silly question, or I'm missing an obvious detail.  My nomenclature may be off as well, hopefully I convey my issue.

For classification problems (let's say we're using Logistic Regression, Decision Tree, or another common approach), is there a way to have RapidMiner understand a specific class to be the "class of interest"?  That is, when I run performance operators, I'd like to be sure that my Sensitivity, Specificity, True Positive, etc. rates are all reported with respect to the focal class that I specifically identified.

Is there a specific Operator that allows for this?
Is there a "clever workaround" for dealing with this?
Something else?

Thanks!

    Thank you!  I was searching using any verbiage I could imagine, but "map" wasn't one I thought of, thank you very much!  Easy solution!

    Hi @abaker,
    9.3 has a new feature to explicitly state the positive class in Performance (Binominal). It is currently in Beta.
