Hi Dominik, As you wrote earlier, the first problem can be resolved by using delete.vertices=FALSE when calling subgraph.edges (sorry, I thought this is the default).
Re the second problem: use get.edgelist(graph, names=FALSE); this will give you a numeric edge list and this is what you need in later steps. Best, Tamas _______________________________________________ igraph-help mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/igraph-help
