Edit Question
Title
Body
Say I have this example graph, i want to find the edges connected to vertex 'a' d <- data.frame(p1=c('a', 'a', 'a', 'b', 'b', 'b', 'c', 'c', 'd'), p2=c('b', 'c', 'd', 'c', 'd', 'e', 'd', 'e', 'e')) library(igraph) g <- graph.data.frame(d, directed=FALSE) print(g, e=TRUE, v=TRUE) I can easily find a vertex: V(g)[V(g)$name == 'a' ] But i need to reference all the edges connected to the vertex 'a'.
