Dears, we have been working with unscrambler for IR spectra (where we preteat the spectra with first and second derivatives and smoothing before doing anything else with the data... is there a way do to the same with RM?
Here is a picture of what I would like to do (go from A to C and then start the DM

)

And... at unscrambler I normally don't discretize the label column, use the numeric values. At RM only working nice creating cathegories (low, medium, high), which is fine too, but... wonder if I could do it the otherwise around too, or is this computationally too intensive.
