Hi,
in applied work with a 'foreign' block where data is sent to R, I had
the case of a string-valued series which was transferred as strings and
then caused hiccups on the R side. I solved the problem by copying on
the gretl side the series to another one, which then --as described in
the guide-- only contains numbers.
However, I'm wondering whether it is an intended feature that the
"gretldata" object in the R context can contain non-number items?
Loosely related observation from working with 'foreign' and getting
errors: after an error occurred inside the block, re-starting the
containing hansl script sometimes then seems to stumble over leftovers
of the previous error. The cleanup of the transfer-to-R temp files is
not sufficient after an error, it seems. Having a "clear" statement at
the top of the script isn't enough, apparently. Doing a separate "clear"
in the console sometimes helps, and sometimes a gretl re-start is
necessary, too.
thanks
sven
