I'm new in igraph and R and i'm having some trouble to add weights is edges on a graph that I created. The only way that I found to do it is by adding it one by one, like this:
forqueta.ligeiro[1,2,attr="weight"]<-sum(custos[1,],na.rm=T)
forqueta.ligeiro[2,3,attr="weight"]<-sum(custos[2,],na.rm=T)
forqueta.ligeiro[3,4,attr="weight"]<-sum(custos[3,],na.rm=T)
and so on...
My problem is that I have a big graph, with at least 90 edges, and I want to know if there's a more automatic way to do it, like inserting a vector with all my weight on the edges of a graph.
Thank you!
