How to define subset of attributes to apply some operator at it.

Legacy User

Hi, i am just learning(about 2 days) to work with RapidMiner a i couldn't answer one question. How to define some subset of attributes to apply operator only on this specific column. For example in my case i have 26 attributes(17 nominal a 9 numeric) and i want to apply Nominal2Binary but only at 2 specific nominal attributes, or i want to use frequency binning only on 1 numeric attribute and i dont want to affect other same-type attributes
Can somebody point me to right direction?

Hi,

I think you'll need the AttributeSubsetProcessing operator, using a regex to specify the attributes you want to change.
