Re: [igraph] accessing edges from the nodes

[Gábor Csárdi]

You should not be ashamed, we should be ashamed that this is not an
easy and straightforward thing to do. Anyway, here is how to do it:

g <- graph.ring(10)
E(g)[ 1 %--% 2 ]

What you get is an edge sequence, it is printed differently, but in
reality it is a numeric vector, just call as.vector() on it to get a
proper numeric vector.
