Hi,

a colleague made me notice the stack() function for handling a specific case of panel data import in section 4.5 of the guide. I must admit I have never been aware of that function, and I have one or two questions here.

First, it does not appear in the function index (Gretl Command Reference / Functions proper, or in the built-in function documentation). Is this an oversight, or is there a deeper reason?

Secondly, it is well documented in the guide section 4.5, but it appears to be a strange beast: It is not a gretl command (gets function arguments in parentheses, for example), but there are double-dash options such as --offset or --length. I don't remember to have seen something like this in gretl (or hansl) before.

I guess the story here is some path dependence of the early days, but I wonder if this area could be cleaned up somehow?

thanks,

sven
