[R] controlling the edge linewidth in Rgraphviz

[Adrian Dragulescu]

Hello,

I would like to have different linewidths for the edges of my graph.  I
read the documentation but could not find how to control this.  On the
Graphviz help page I've seen that there is something called "penwidth" but I
could not find it in the R edge attributes.

Thanks a lot for any help.
