Hey, all.  I'm looking for packages that are good at two things

1) Drawing directed graphs (i.e nodes and edges), both with single  
and double headed arrows, as well as allowing for differences in line  
width and solid versus dashed.  Note: I've tried Rgraphviz here, but  
have run into some problems (which seem fixable and I may go with it  
in the end), and it doesn't satisfy need # 2 (which would be ideal if  
there is a package that does both).

2) Allowing a user to create a directed graph, and have some text  
object created that can be reprocessed easily reprocessed into a  
matrix representation, or other representation of my choosing.   I've  
tried dynamicGraph, but it seems buggy, and continually either  
crashes, behaves very erratically (nodes disappearing when I modify  
edges), nor is it clear from the UI how one outputs a new graph, nor  
how one even accesses many graph attributes.  This may be my own  
ignorance on the latter.

Do you have any suggestions?

Thanks!
