[R] Graph in R with edge weights

[Ivan Alves]

Hi Arthur,

I was asking the same thing and came across the following (your need the "sna" library).

http://students.washington.edu/mclarkso/documents/gplot%20Ver2.pdf

Take a look at the edge.lwd and vertex.cex examples of the function gplot. You can use vectors for the different nodes.

Kind regards,
Ivan
