[R] [Fwd: Re: controlling the edge linewidth in Rgraphviz]

[Florian Hahne]

Hi Adrian,
even better would be this:
1.) Install the latest Rgraphviz devel version
2.) Use the new API for graph rendering:
library(Rgraphviz)
example(randomEGraph)
x <- layoutGraph(g1)
graph.par(list(edges=list(lwd=2))) # if you want to set lwd=2 for the 
whole session
# or if you just want to change this for your one graph:
renderGraph(x, graph.pars=list(edges=list(lwd=2)))

There is a Vignette that explains all the new stuff.
