I am pretty beginner so excuse me if this is a remedial question, I have tried googling the answer and haven't been able to find the answer.
I am working with survey data that has two waves. I want to only use the participants that answered the survey for both waves and throw out the ones who did not do the follow up. I have both waves merged into the same large set, so ideally what I want to do is delete out any of the participants in the first wave that do not have follow ups attached.
