Re: [igraph] changing widht and height of the igraph

[Gábor Csárdi]

Here is my example again, just to have it on the list.

library(igraph)
g <- graph.ring(10)
png("ring.png", width=300, height=150)
par(mar=c(0,0,0,0))
plot(g, asp=0, margin=0)
dev.off()

If the nodes are still on top of each other, then you have three options:

1. make the figure bigger
2. make the nodes smaller
3. play with the layout generator parameters to make edges shorter,
assuming they are too long now.
