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