Note that we can't comment on what you didn't understand if you don't show us any code. I wouldn't -stack- this. I would -reshape-. The main reason is that -reshape- is very useful, but you need to practise so that you can get used to it. I assume an identifier -id-. If one does not exist, create it. gen id = _n reshape long v, i(id) You can -stack- too. stack v1 v2 v3, into(v4) clear I don't understand why the duplicates in your first example don't show up in your second. I assume that's meaningless unless you explain to the contrary. Nick n.j.cox@durham.ac.uk Enayetur Raheem I was trying to transform the following data v1 v2 v3 11 12 13 11 12 13 11 12 13 21 22 23 21 22 23 21 22 23 31 32 33 31 32 33 31 32 33 into a single variable, such as v4 11 12 13 21 22 23 31 32 33 I tried the -stack - command, but could not get it done. I am very new to Stata, so I am not aware of many commands. Any suggestion will be much appreciated. * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
