Assume I have a dataset with the two variables "number" and "text". They contain observations like (1, "one"), (2, "two"), (3, "three"), etc. Now I would like to write a specific value into a local macro. For example, I might be looking for the text that goes with the observation with number==2, and would like to assign that value to a local macro. Very amateurishly, I was looking for code similar to the following: > > local v=text if number==2 Assuming there is only ever one value of "text" that corresponds to each "number" you can... levelsof text if(number == 2), local(t) di "`t'" Neil -- "One should as a rule, respect public opinion in so far as is necessary to avoid starvation and to keep out of prison, but anything that goes beyond this is voluntary submission to an unnecessary tyranny, and is likely to interfere with happiness in all kinds of ways..." - Bertrand Russell Email - nshephard@gmail.com Website - http://slack.ser.man.ac.uk/ Photos - http://www.flickr.com/photos/slackline/ * * 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/
