[SOLVED] Discretize by User Specification: multiple class problem

Hi everyone,

my question is about the operator "Discretize by User Specification" in order to discretize numerical values.

Let's assume I want to discretize the four cardinal directions (north, east, south and west) as follows:

315-45: North
45-135: East
135-225: South
225-315: West

and in RapidMiner (at least I assume) as follows: class namesupper limitNorth45East135South225West315NorthInfinity now the problem is that the first "North" class will be overwritten with the second "North" class and the values appear as missing values "?".

Is there any workaround?

Cheers Q-Dog
