This function and all of its descriptions have been obtained from the igraph package.

```
betweenness(
graph,
v = V(graph),
directed = TRUE,
weights = NULL,
normalized = FALSE,
...
)
```

- graph
The graph to analyze (an igraph graph).

- v
The vertices for which the vertex betweenness will be calculated.

- directed
Logical, whether directed paths should be considered while determining the shortest paths.

- weights
Optional positive weight vector for calculating weighted betweenness. If the graph has a weight edge attribute, then this is used by default. Weights are used to calculate weighted shortest paths, so they are interpreted as distances.

- normalized
Logical scalar, whether to normalize the betweenness scores. If TRUE, then the results are normalized.
