How to create a categorical array
To create a categorical array click the New Variable button in the bottom left of the Crunch window. Then select Build Array Variable and select the variables you want to combine into a new array variable. If you don't see the variable you are looking for it is likely because the variable needs to be converted into a categorical variable (to convert a variable's type, please reach out to an editor who uploaded the dataset or email support@crunch.io).
Give the variable its own name and click Save to create the variable.
