see

To plot to the output window, wrap add rk.graph.on() / rk.graph.off() around 
the plotting statement(s). Assuming you have a preview box (easy enough to 
add), that will be

function doPrintout (full) {
  if (full) {
    echo ('rk.header("Some interesting plot")\n\n');
    echo ('rk.graph.on()\n');
  }

  echo ('try ({\n');
  echo ('\tprint(qplot(mpg, wt, data=mtcars))\n');
  echo ('})\n');

  if (full) {
    echo ('rk.graph.off()\n');
  }
}

Regarding the rkward::plot_options embeddable plugin, I'm not quite sure, 
which options are usable with ggplots. Many (like xlim, ylim) should work 
fine, though, so consider adding this, too, as outlined in the documentation 
linked to, above.

Regards
Thomas
