[R] linewidth in Rgraphviz

  I'm an Rgraphviz newbie trying to figure out how to do some things/whether
they are possible.
  Apparently graphviz does allow you to modify line widths of edges: see


(although it looks a little obscure even in graphviz).  [As discussed in the
above, the "weight" parameter in Rgraphviz sets the parameters of the graph
algorithm, NOT the linewidth of the edge itself.]

   I can probably figure this out given enough hours, but if someone were
to put together an example in a few minutes (or know that it's impossible
or very difficult) I would be grateful ...
