Re: [Gretl-users] error with null list

Allin Cottrell schrieb: Thanks! Ok, I found out about nelem() etc. in the meantime, so it's easy to do what I want anyway. I now have a prototype working of a gretl function package which passes the user input and the data to a NumPy (numerical python) Vecm class to do some calculations which are not implemented in gretl natively, and python then stores the results in a gretl script file, such that they can be loaded into gretl easily. I call this rudimentary framework py4gretl :-) My plan is to make the whole thing available for those who are interested shortly after gretl 1.6.1 comes out. (Well, don't expect too much, it's mostly for myself...) In relation to all that I have a short wishlist for Allin and Jack: 1) Could 'include' and/or 'run' also be made available inside functions? That way the output from my python program could be read into gretl automatically via a temp script file. I guess this should even be less problematic than the '!' issue we discussed earlier. 2) IMHO the 'outfile' command should behave like 'store' (after the recent changes in cvs) with respect to where it creates the file, including honoring the user preference setting, like we discussed for 'store' in a recent thread. 3) less important: currently it seems impossible to specify an empty list in the function package GUI, although it would be useful as an option. Thanks a lot, Sven
