[Gretl-users] aggregate by

Hi I want to thank again all Gretl developpers for this wonderful software. I try to port some of my R code into Gretl and I miss few things. For example, what is the easiest way to perform some aggregate operation in Gretl like : - aggregate(x, by = y, FUN) in R or - egen z = FUN(x), by(y); in Stata or - SELECT FUN(x) GROUP BY y in SQL It looks like I miss something in the documentation. Thanks again -- Ahmadou H.
