[Gretl-devel] should nelem() be defined for series?

Hi, this question is prompted by the very recent tip for the aggregate() function that the position of the count column is at nelem(byvar) + 1. (Where the "byvar" name stems from the help text.) I realized that this will fail if the byvar argument is only a single series. For example: <hansl> open denmark list L1 = LRM eval nelem(L1) # 1, of course eval nelem(LRM) # data type error </hansl> I understand that nelem() on a series is ambiguous, because it could be understood to mean the observations, like in nelem({x}). But we also have the nobs() function for that. I wonder if this issue may become more relevant with the recent overloaded "numeric" argument possibility? Maybe also the other way around, in that nelem(x) should become an alias for nobs(x) for a series because of that? Hm. (BTW, the nelem doc needs updating, because it also works for a string.) thanks sven
