Here is the IRFplot function I wrote it works badly when pdf

The second-last line is the problem: gretl's --output=display
option for the "gnuplot" command only works for PNG files. We
grab the PNG and render it into a a gretl-controlled window.
If you drop that line the output to file should be OK.
