Re: A wish to save .gretl dataset from a scrip
by Fred Engst
Allin, you are my hero!
I hope it wasn’t too hard to do, just to fulfill my wish.
I tried and it work like a charm!
I can’t thank you enough for this.
Without this, if I discover an error in the model I did, I would have to redo the last part manually for all the students.
Now it is only a click of the button after I made the corrections.
The power of gretl just getting better and better.
Best,
Fred

As is, I need to save each dataset manually, and it is a bit time consuming when there are more than just a few students. I wish I can do this through a script, perhaps using gretlcli to do that, if any of you can suggest a way.

sven, don’t hold back on any suggestions, please!
Don’t we want to vectorize as much as possible in our coding to make it more compact, in the tradition of one-liner?
