# centr_betw

##### Centralize a graph according to the betweenness of vertices

See `centralize`

for a summary of graph centralization.

##### Usage

```
centr_betw(graph, directed = TRUE, nobigint = TRUE,
normalized = TRUE)
```

##### Arguments

- 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 passed to the

`betweenness`

function.- normalized
Logical scalar. Whether to normalize the graph level centrality score by dividing by the theoretical maximum.

##### Value

A named list with the following components:

The node-level centrality scores.

The graph level centrality index.

The maximum theoretical graph level
centralization score for a graph with the given number of vertices,
using the same parameters. If the `normalized`

argument was
`TRUE`

, then the result was divided by this number.

##### Examples

```
# NOT RUN {
# A BA graph is quite centralized
g <- sample_pa(1000, m = 4)
centr_degree(g)$centralization
centr_clo(g, mode = "all")$centralization
centr_betw(g, directed = FALSE)$centralization
centr_eigen(g, directed = FALSE)$centralization
# }
