Selecting subsets of variables

[Susana0000]

Hello everyone,

I'm trying to create subsets of my variables in groups of 6.

I'm doing this to check that an observation has at least 6 variables that are complete to include in an evaluation.

Should I use ALLCOMB? If so, how? Because I've been seeing a lot of cryptic code and I can't seem to understand it.

Thanks

I don't understand this. Please be more specific and include both sample data and your desired result.

Makes it much easier to provide a usable code answer.

Typically, variables are columns and observations are rows.

Are you trying to create subsets of observations or variables?
Show us a small example - make fake data if you cannot share your real data. It should cover as many cases as possible, for example cases where all values are missing, where none are missing and everything in between. Show both the input and expected output, ideally they align so that the input would generate a specific output.
