[R] Standardized coefficients (std.coef) in graphviz from path.diagram()

[Christopher David Desjardins]

I was wondering if there was a way to add the standardized  
coefficients from SEM that I get from running std.coef() to my graph  
that I create with path.diagram() for graphviz? Right now the only way  
I know how is to edit the values in a text editor after creating the  
graph.
    Thanks,
    Chris
