[Gretl-users] Re: Problem running "foreign language=R --send-data" in Ubuntu
Hi Allin,
I realise that I didn’t give all the information. I attach a zipped minimal version, in
which the source line has been replaced by the explicit R function which I use to retrieve
the data. You will see that the initial dataset contains three string series in which the
first variable SLIST is a list of variables to be downloaded from the FRED database. I
have reduced this to three, and taken out other irrelevant material in the script. The
datafile from which the script reads the variables is in the directory test/data.
As I mentioned this script works perfectly on a Mac with Gretl 2025b but fails in Ubuntu
24.04 with Gretl 2023c.
I hope this give the necessary information.
Many thanks for any suggestions,
Roland

Roland, can you tell us, where is "functions/data_management.R" coming
from, and what's the content of gretldata$SLIST? As things stand we're
not in a position to replicate this issue. I'd also note, there are
some unclosed quotes above that would presumably halt execution in R,
but maybe that's just a matter of transcription.
