Thanks again. The minimal-invasive thing to do would be to just mention
this fact in the R functions / R library section in the user guide.
Not sure right now about error messages from (lib)R, but I think they do
get through to gretl?
My understanding is that if a pre-defined R function is called
directly from gretl, error messages from libR will go to stderr as
things stand, and will therefore be invisible in the gretl GUI. But in
standard foreign-block mode you should see error messages from R OK.
