|Subject||st: egen fill() for string variables?|
|Date||Wed, 1 Sep 2004 08:50:37 -0700|
I've found the fill() function for egen to be a very valuable tool, but I recently found it doesn't work for repeating patterns of string values. For example, if I wanted to generate a variable containing "cat, dog, rat, fish" for a set of 100 observations, I would first -expand- the observations to 400 by using
and then using my idealized egen situation I'd type
.egen str4 animal = fill(cat, dog, rat, fish, cat, dog, rat, fish) /*possibly with double quotes enclosing the strings - e.g. "fish" */
does such a command exist somewhere?
If not, would a workaround such as the following work? (I'm not at a Stata enabled machine this morning)
.egen animal = fill(1,2,3,4,1,2,3,4)
.label define critter 1 "cat" 2 "dog" 3 "rat" 4 "fish"
.label value animal critter
.decode animal, gen(str_animal)
