newbie igraph user here. i'm trying calculate betweenness values every segment (edge) in street network. ideally restrict calculations paths of less x metres considered. igraph::edge.betweenness.estimate function has cutoff argument restricts steps ( turns ) know if possible use metric distance instead. so far closest question have been able find http://lists.nongnu.org/archive/html/igraph-help/2012-11/msg00083.html on igraph help, , suggests might not possible. i have been using network aspatially, simple graph, have attribute of street segment length - lnklength . reading other stackoverflow posts possible use spatial networks igraph (with of spatial packages). if lnklength used weight network solve problem? if has ideas i'd grateful hear them. data <- data.frame( node1 = as.factor(c(aa, ab, ac, ad, ae, af, ag, ah, ai, aj)), node2 = as.factor(c(ba, bb, bc, aa, ab, ac, ba, bb, bc, aa)), lnklength =as.numeric(c(23.05, 42.81, 77.08, 39.63, 147.87, 56.46,...
