does it help to change the font size? View->Enlarge Font / Shrink Font, 
default shortcuts Ctrl+ and Ctrl-.

Settings->Configure RKWard->Output->Graphics .

When writing your own R code, you can also pass parameters width and height to

The development version has some support for adding custom HTML-headers to the 
output document, e.g. a custom CSS-definition. If it really bugs you, you 
could also modify the (extremly basic) default CSS file we ship. Use
View->View Document Source on the output window to find out where this is 
located on your system.

See above, the defaults are configurable. It may make sense to provide an 
additional option to copy on-screen graphs to the output in their current 
size. Feel free to submit a feature request 
(http://sourceforge.net/tracker/?atid=459010&group_id=50231&func=browse) so 
that we will be reminded about this, in time.

I did not actually try this code (if you can, please try to condense your 
examples to the absolute minimum, and use data from the datasets-package; this 
really saves us valuable time), and maybe I did not understand the problem.

What this will do is:
1. Create the plot in the default device, i.e. on-screen.
2. Copy the onscreen plot to the output window.

I guess, instead, you were looking for:
  rk.graph.on ()
  plot (c, align = "left")
  rk.graph.off ()
