Re: st: help merge

[David Kantor <dkantor@jhu.edu>]

Indeed, -keep()- is a feature that is new in Stata 8.

In an earlier Stata version, you would need to do what Oscar Alberto Budar 
Mejía had suggested. Here's a somewhat modified variant on that:

use master;
keep the variables you want to take, plus match-key variables;
sort on the match-key variables;
save as a tempfile;
use analytic;
merge using the tempfile created above;

I used to do this all the time.  Thus I am very please that they added the 
-keep()- feature.

This also reminds us to state what version of Stata you use (if it is not 
the latest) when posing a question.
