Dear all, Since I didn’t receive any feedback, your help would be very much appreciated. Many thanks in advance and best regards, Chris Von: igraph-help <address@hidden> Im Auftrag von address@hidden Dear help community, Many thanks for providing your help! I currently compute centralization measures for vertices, in particular centralization degree, betweenness and closeness. I compute graphs for directed and undirected vertices. While the centralization.degree and centralization.betweenness function make a difference in their computed results for directed and undirected graphs, centralization.closeness apparently does not. Then I also tried the function “closeness” provided by you and also this does not seem to take into account differences for directed and undirected graphs. May I ask you kindly, to provide me your thoughts on this? This would be very much appreciated! The exemplary edgelist looks like this: I use three different function to get my graphs:
Different variations of the centralization.closeness function seem to not make any difference as far as directed and undirected: For closeness, it seems “in” and “out” as variations do make a difference, while again directed and undirected is not differentiated in total: Many thanks for your response it advance and have a great day! Best regards, Christopher Lonzius |
