Dear all,maybe this is a simple question, but I don't know how to overcome myproblem.I have a variable time and I should generate another variables equal to time when another variable (code) is equal to 1 or 2. However, I don't know how to instruct stata for this. I tried with: gen time1= time if code==1 & code==2 but of course I will have all missing values. Thus, I created two variables: gen time1= time if code==1 gen time1= time if code==2 but I would like to merge the values of the two variables at this point. Any idea of how to do this? Thank you.
