Ah, I see. I just was not sure about the syntax. I was reading my graph
from a .csv as following:
reader = csv.DictReader(open("pr-network-demo.csv"), dialect="excel")
g = igraph.Graph.DictList(vertices=None, edges=reader)
Adding the *directed=True* argument fixed the problem.
Thanks very much for this suggestion!
