centr_betw(graph, directed = TRUE, nobigint = TRUE, normalized = TRUE)
graph | 
 The input graph.  | 
directed | 
 logical scalar, whether to use directed shortest paths for calculating betweenness.  | 
nobigint | 
 Logical scalar, whether to use big integers for the betweenness calculation. This argument is deprecated in igraph 1.3 and will be removed in igraph 1.4.  | 
normalized | 
 Logical scalar. Whether to normalize the graph level centrality score by dividing by the theoretical maximum.  | 
A named list with the following components:
res | 
 The node-level centrality scores.  | 
centralization | 
 The graph level centrality index.  | 
theoretical_max | 
 The maximum theoretical graph level
centralization score for a graph with the given number of vertices,
using the same parameters. If the   |
