edge sequence by vertex name

Question

Hy Everybody!

Well, I'm working with the Igraph package, and i'd like to pick the edges by the name that I've assigned to their vertex, in a tiny example..

library(igraph)

g <- barabasi.game(8)

labels<-c("G1","G2","G3","T1","T2","T3","H1","H2")

V(g)$name<-labels

Now My edge list hast this form

> E(g)
Edge sequence:

[0] G2 -> G1
[1] G3 -> G2
[2] T1 -> G2
[3] T2 -> G3
[4] T3 -> G1
[5] H1 -> G1
[6] H2 -> H1

What i want now is to find a way of, instead of using this

E(g)[1%--%2]

doing something more like E(g)[G2%--%G1] (calling the vertex by the name i've assigned), or an equivalent way of knowing some edges attributes by the name of the vertex involved

Thanks in advanced,
