Hi,
I've got an undirected graph that when I calculate closeness or
betweenness centrality it crashes R without an error message or explanation.
I'm creating the graph using an edges list, and use that exact script
with other lists and it works. So I guess there must be some problem
with the graph for that particular set of edges.
Querying 'is.simple(g)' returns FALSE, so that could be the reason for
the crash?
But after doing 'simplify(graph, remove.multiple = TRUE, remove.loops =
TRUE)' I still get FALSE result from is.simple.
Are there other conditions that make a graph not simple?
Are there special restrictions for graphs to be used in closeness and
betweenness centrality that I'm forgetting?
Thanks in advance,
Jorge
