I actually cannot reproduce this. The following all works fine: library(igraph) g <- graph.ring(10) g[1,2,attr="weight"] <- 0 g el <- get.edgelist(g) g[from=el[,1], to=el[,2], attr="sim"] <- seq_len(ecount(g)) g V(g)$name <- letters[seq_len(vcount(g))] el <- get.edgelist(g) g[from=el[,1], to=el[,2], attr="sim"] <- seq_len(ecount(g)) g So I'll need some information on what exactly you did, including toy data that shows the problem.
