Reverse map a nominal to numerical transform
I am using K-means to cluster the data. To do so, I have transformed my nominal values into numerical ones using the Nominal to Numerical operator, but using the coding type parameter set to "unique integers." How do I reverse this transformation so on output I can see what these values were in the clusters before they were transformed. For example, if "sandwich" gets mapped to 0, I would like to reverse map 0 back to sandwich.
