The plugin is in Spanish, but I'm translating it to English now, and I will
share it in a few weeks.
The code for generating the graphic it's a bit complicated, and that no helps
to understand the problem.
So I've tried to do a simple example with your code, just putting it inside the
doPrintout(full) function:
function doPrintout (full) {
echo ('print(qplot(mpg, wt, data=mtcars))\n');
}
and I get the graphic in a new window, but no in the output window rk_out.html
Thanks!

As Meik has pointed out, some example lines of (generated) code would be
useful. But as a first guess, the gotcha is auto-printing:
ggplot2 functions, in contrast to "regular" plotting functions, do not
actually "have the side-effect" of creating a plot, but rather they create an
object, that - when printed - creates a plot. When running code on the top-
level, line by line, values get auto-printed. But once you leave the top-level
(as does all plugin code), the difference becomes visible. Consider these
examples:
{ qplot(mpg, wt, data=mtcars); 1 }
{ x <- qplot(mpg, wt, data=mtcars); 1; x }
{ print(qplot(mpg, wt, data=mtcars)); 1 }
The third example should point to the correct solution: Call print(),
explicitly, to make the plot show up.
