WebNote that igraph is a CRAN package, not a Bioconductor package. Your graph probably has more than 1 edge between the 2 same nodes. That happens when you have more than 1 interaction type between a given TFLocus and a given TargetLocus. It has nothing to do with the fact that the graph is directed or not.

WebIt is a way to reference a sequence of vertices or edges independently of the graph. While this might sound quite mysterious, it is actually very simple. For example, all vertices of a graph can be selected by igraph_vs_all () and the graph independence means that igraph_vs_all () is not parametrized by a graph object.
