If I have a directed graph and want to label or color the two edges
between two vertices differently, how can I make them arcs?
example
Take your g from graph.data.frame and add an edge
>* g <- add.edges(g, c(0,1), attr=list(same.dept=FALSE, friendship=2,*
advice=1))
>* E(g)$label <- E(g)$advice*
>* plot(g)*
I would like to have different widths or colors for the two edges
between A and B.
Is it possible to show them separately?
Thanks in advance,
David L. Reiner
