Transform one categorical variable into a binary categorical variable

Hy,

I'm looking for a solution to transform one categorical variable into a binary categorical variable. The goal of this is to do an Association Analysis.

I know it's possible to create the variables manually but i search a macro which could do this for me.

My variable is the number of department and there are 99 possibilies in one categorical variable.

If you can avoid me do this manually, i will appriciate

Thanks for your help !

Glad to hear it worked. Aside: one tip/trick I've seen is that you can open a .yxmd or .yxmc in a text editor, and edit the first line to adjust the workflow/macro version. As long as it isn't using anything specific to the more recent version, that's an easy way to "roll back" the version.

Great question. The attached macro should expand a given field into binary fields as you ask. Be careful in using it though; if you have a lot of possible values in the "field to expand" it could result in an enormous number of columns. You mentioned only having a hundred possible values, so for that problem this macro should work fine.

Hope that helps!

[EDIT: fixed to have False instead of Null values.]

PS, an example simple workflow using the macro is attached here; (I tried attaching a .yxzp in the previous post but it didn't like the .yxzp for some reason).
