Graph in R with edge weights
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

Can you please show code example, how to draw graph with some nodes and edges, but with weights. I only found here http://www.bioconductor.org/packages/release/bioc/vignettes/Rgraphviz/inst/doc/Rgraphviz.pdf- Using edge weights for labels, but... Here an example:
library("graph"); library(Rgraphviz)
myNodes = c("s", "p", "q", "r")
myEdges = list(
s = list(edges = c("p", "q")),
p = list(edges = c("p", "q")),
q = list(edges = c("p", "r")),
r = list(edges = c("s")))
g = new("graphNEL", nodes = myNodes,
edgeL = myEdges, edgemode = "directed")
plot(g)
but how about weights? Thanx. [[alternative HTML version deleted]]
