[BioC] Rgraphviz for Windows

[Wolfgang Huber]

Hi,

An inelegant but probably functional workaround is to communicate with 
graphviz through files. I don't know whether there is already  an export 
function from "graph" objects in Bioconductor to .dot files, or whether 
someone would like to contribute one?

.dot files  can be read from graphviz's dot, neato etc. on the command 
line (and you may even automate that using the "system" command in R). 
It's not pretty, but works.

Best wishes
  Wolfgang
