[for a self-contained script a line like "include yahoo_get" would have to be included at the top]Hi,
There appears to be a strange error related to the function package GUI in Package: yahoo_get 3.9 (2026-01-20) for gretl 2026a.
When I run the following script, everything works correctly:
nulldata 1000 setobs 5 2022-06-01 # a daily dataset should already be in place delete index series apple = yahoo_price("aapl") # get Apple, adjusted price only list L = yahoo_full("msft")
However, when I access the same functionality through the GUI (as shown in the attached file), I receive the error message:
"Argument 1 (ticker) is missing."
Hi Yi-Nung, good to hear from you.
I'm not seeing this problem on a recent snapshot from March 25th on Windows. Don't know if there was a recent fix in that area affecting yahoo_get, but from the changelog it's not apparent.
cheers
