Even better, -tab, generate()- will do it for you in one line!
thx for your advice, nick. sorry for being a bit too imprecise.i have 2 tables: table 1 (dataset) with some variables incl. one variable
"atc-code" with 700+ agents (14000+ rows). for counting that, the "tab, gen()-thing" is perfectly suitable.but: i have table 2, a specific subset of agents (200+) and their atc- code,
one agent = one row. my working question: how many times is any of the agents in table 2 represented in the variable atc-code in table 1. hope, i sort of disentangled the problem a bit. thomas -- Dr. Thomas Zimmermann Institut f.
