[Gretl-devel] foreign block and string-valued series

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
