 Dear all,
 
 I am using R 2.2.0 with latest releases of bioconductor and other packages (especially Rgraphviz). I am interested in drawing weighted graphs using Rgraphviz. It works perfectly fine if I change colour (color option), labels (label option) of the edge. But if I try to add weight (weight option) R exits with "segmentation fault"
 
 I would be grateful  to have any comments.
 
 Thank you and Regards,
 Kaustubh
