Very new to RM making headway slowly.

I have split a column such that the one of the new columns is a column of numbers this field is set automatically to `polynomial`.

How do I set it to `Numerical` or even better `Integer`?

I have tried `Geuss Type` but this did not work

Thanks

Hi,

you can use the "Nominal to Numerical" operator, followed (if desired) by the "Real to Integer" operator.

Hello

We're suffering from cross-post syndrome - this also appears on StackOverflow where the answer was that there was an accidental missing value in one of the examples that caused the Guess Types to fail.
