So if I understand correctly: - I can use $model directly (without extra function arguments) within the public functions of the package that I assume will be invoked via the GUI. - Or is the designation of "menu-attachment" for the package then mandatory? (In the package guide it says it's optional, but this may be a special case.) - It is probably recommended to specify such functions as "menu-only" in the package? - Just to be sure: $model within a function in a standard context is only valid if inside the same function something was estimated, not outside the function, right? thanks, sven _______________________________________________ Gretl-devel mailing list Gretl-devel(a)lists.wfu.edu http://lists.wfu.edu/mailman/listinfo/gretl-devel
