Good Morning!
I am graduating from PUC Minas Brazil and my work theme of completion is on
the R language, specifically on the package IGRAPH. I wonder if you can
help me understand how R calculates the centrality of edges in the function
below:
edge.betweenness (malha)
[1] 0 0 0 0 5 5 8 8 0 0 5 5 8 8 9 9
Attached hereto that the model did with the function result.
Many thanks and hugs!
