I think the previous suggestions have solved your problem, but just in case you need even more flexibility, you could try using the cairo graphics device (cairoDevice) in conjunction with the GdkPixbuf bindings provided by RGtk2. This allows fairly advanced image manipulation operations (scaling, compositing, ...) on R graphics.
