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."
I conducted quick tests on versions 2025a
and 2025b, and no such error occurred.
However, version 2025c also produces the
same error message:
"Argument 1 (ticker) is missing."
Is there something changed since the version 2025c?
best regards,
Yi-Nung
