Hello, What precisely does igraph_transitivity_undirected() compute for directed graphs?
The C documentation states that "Directed graphs are considered as undirected ones." but this is not exactly the case. With an example using the R interface (for simplicity), > g<-make_graph(c(1,2, 2,1, 2,3, 3,1)) > transitivity(g,"local") [1] 0.3333333 0.3333333 1.0000000 > transitivity(as.undirected(g),"local") [1] 1 1 1 Can someone clarify what precisely is computed in the directed case?
