April 2010 22:15 To: statalist@hsphsun2.harvard.edu Subject: st: Placing a string variable in a local/global Dear Statalisters, I am assigning the names of certain observations from variable X to a local/global with the command: local n = X[_N]. Say that now `n' has the string "bear" stored in it. Next I load a larger data base where variable X has several string observations named bear among others. For the final step I am trying to record the observations from variable Z where `n' = X in a variable y. My code is this: local n = X[_N] use "C:\Users\George\Desktop\Methodology\Final data1.dta", clear gen y = Z if `n' == X However when I do this, I get the error message: unrecognized command: bear Do you know how I could store observations from X so that when I load a larger data set I can use them to see how many similar observations I have in the larger data set? Thank you a lot for the help, George * * 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/ * * 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/ * * 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/
