Hello, I would like to compute all the geodesic paths among all n vertices of a graph g and I have two questions:
I understand that running > get.shortest.paths(g, i, 1:n) gives all the geodesics from vertex i to all n vertices of the graph. However, running something like > get.shortest.paths(g, 1:n, 1:n) does not work. 1. Is there a way to get all geodesics together at once, instead of running get.shortest.paths(g, i, 1:n) separately n times? 2. Since, in my data, vertices have an attribute (say, taking values 1, 2, 3, ...), is it possible to filter out from the outcome of the previous computations only those geodesics which contain at least one intermediary vertex taking a particular value of the attribute? And how can I do this? Thanks in advance for any assistance you might be able to give me. --Moses _______________________________________________ igraph-help mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/igraph-help
