Hi everyone, I am new to field of data mining as well as particularly using R respectively RWeka for writing my master thesis.
I intend to create some specific J48 classification trees with the RWeka_classifiers_tree function. When I run the source code it says “cannot handle numeric class”. I therefore checked the arff-file and indeed there it says that the class variable is numeric although it only contains 0 and 1. In a next step I tried to Discretize my dataset but received the same error message. I googled the issue several times and also read about the filter function in WEKA but did not know how to use it and unfortunately did not find a proper solution. So – how can I transform my class variable from numeric to nominal / binary, I just don’t get it?! As I said, I am new to all of this and so appreciate anything little which helps!
