Re: [igraph] a problem with simplify()

[Simone Gabbriellini]

Hi Gabor,

I am on 0.6 right now. thanks I'll use the workaround, I just need to kill 
loops. Is there any better way to do this than:

for (i in 0:length(E(g))){
        if is.loop(g, eids=i){
                delete.edges(g,i)
                }
        }

best,
simone
