adding labels to a polynominal variable

I have a polynominal variable, Income, with 4 categories: <25, 25-49, 50-75. 75+. I want to add a label to each category. For example, for <25, I want to add (or replace it with) a label " Low Income". What is the simplest way to add labels to a polynominal variable?

    you can easily rename/replace your categories with other values by using the Replace operator.
    To specify an attribute as label, you can use the Set Role operator and select "label" as target role. Be aware that each example set can only has one attribute marked as "label".

    Best,

    @Mori111 yes as @David_A said, 'Replace' will work. So will the 'Map' operator. Or you can do it in Turbo Prep. :smile:

    Great Thanks. MAP operator works better because at the same time you can replace all values with labels. I haven't tested Turbo Prep yet.
