I will be glad to look into how I can help, but, is there anyone who has been
able to get the combination of Rraphviz and the other pieces to work under
windows?  And, what version of Visual Studio would be appropriate?  I am really
needing back compatibility for 32 bit R 2.11, so if there is an earlier
combination that would work, great.  Also, in a 2008 post Jenny Drnevich posted
help which suggested installing the Microsoft Visual C++ 2005 SP1
Redistributable.  I suppose that is intended to help Graphviz function. Clues
would be appreciated.
