public class NominalToBinary extends Filter implements UnsupervisedFilter, OptionHandler, StreamableFilter
-N Sets if binary attributes are to be coded as nominal ones.
-A For each nominal value a new attribute is created, not only if there are more than 2 values.
-R <col1,col2-col4,...> Specifies list of columns to act on. First and last are valid indexes. (default: first-last)
-V Invert matching sense of column indexes.
