Hi everyone,

I'm new to Rapidminer, so my question might be super easy.


I have a data set with the following Attributes:

  • Model Code (identifies a group of cars)
  • VIN (identifies cars)
  • Part (identifies part of the car: Fender or door)
  • Measuring Point (identifies measuring points at the part)
  • Station (IFC or FQC -> two times of measurements)
  • Rating (Green: 1, Yellow: 2, Red: 3)

I want to get the IFC and FQC rating of one measuring point in one row (--> have 2 new attributes: IFC_Rating & FQC_Rating.

My problem is that the group attribute in the "Pivot" operator can only be one attribute.

What can I do?


Thank you in advance. Johannes

    Thank you for your reply, T-Bone.


    I solved it now this way:

    1. Filter for two example sets (1. all Examples with IFC 2. all Examples with FQC).
    2. Rename "Rating" in both exampleSets
    3. Join them with key attributes VIN, part, side, model code, measuring point


    Best regards.

    Did you take a look at the Aggregate operator too? That allows you to group multiple attributes.
