right now in a recent cvs build I cannot, either. Maybe that was with
1.7.9 on windows. I'll try to check tomorrow.
actually my description wasn't correct, what I remembered was actually
something slightly different: if I do 'heyho=PUNEW(-1)' then the new
variable heyho is subsumed under the PUNEW triangle thing in the GUI. So
gretl realizes that heyho is just a lag of PUNEW and treats it as such.
Now I'm not sure if that's really the intended behavior. Normally if you
create a new variable you want it to be treated as a first-class
variable, even if the contents is just a lag of another variable. AFAIK
the "triangle" GUI trick was introduced as a clever way of making the
lags of a variable that were *automatically created* (for example in the
course of a dynamic estimation) available to the user, without
cluttering the main window.
But, it's maybe not so clear whether it's a bug or a feature. What do
others think?
