Note that this won't work as code like if y = `n' needs to be if y == `n' and forvalue n = 1/n { won't work either. Kim did say "something like". Beyond that, I don't see what point Kim is making here. This code can be collapsed to egen x = rowtotal(d1-d40) Why create separate variables and put them together when you can get there in one? Nick n.j.cox@durham.ac.uk Kim Lyngby Mikkelsen (KLM) If you have consecutive values, you should try to use -forvalue-, otherwise you could try to use -foreach-. If you have y=1, y=2, ..., y=n, you could try to do something like this forvalue n = 1/n { egen x_`n'=rowtotal (d1-d40) if y=`n' } gen x=. forvalue n = 1/n { replace x=x_`n' if y=`n' drop x_`n' } Ora John Reuter I am searching for something that would do the equivalent of an 'ereplace'. I have a set variables for which I generated a -rowtotal- given some condition, e.g. (egen x=rowtotal (d1-d40) if y=1), but then I need to replace some values in that same variable (x) with a different -rowtotal- given a different condition. I dont know how else to explain it except to say that if there were an 'ereplace' command the next command would look like this: "ereplace" x=rowtotal(d2-d40) if y=2 In other words, I need to replace values in x with different sums of variables. I need to do this for a great many conditions so typing out the list of variables to be added for each condition would be a minor pain. * * For searches and help try: * http://www.stata.com/support/faqs/res/findit.html * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
