[Rd] How to document man/*.Rd pages with images?

[Paul Gilbert]

I thought the usual logic was that you might put graphs and images into a vignette, and you might refer to the vignette in an Rd help file, but you would not put the graphs into the help because ? access to the page cannot assume that you actual have a graphics device. Of course, examples in the Rd file can generate the graphs.
