\title{Centralize a graph according to the degrees of vertices}
\usage{
centr_degree(
graph,
mode = c("all", "out", "in", "total"),
loops = TRUE,
normalized = TRUE
)
}
\arguments{
\item{graph}{The input graph.}
\item{mode}{This is the same as the \code{mode} argument of
\code{degree()}.}
\item{loops}{Logical scalar, whether to consider loops edges when
calculating the degree.}
\item{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:
\item{res}{The node-level centrality scores.}
\item{centralization}{The graph level centrality index.}
\item{theoretical_max}{The maximum theoretical graph level
centralization score for a graph with the given number of vertices,
using the same parameters. If the \code{normalized} argument was
\code{TRUE}, then the result was divided by this number.}
}
\description{
See \code{\link[=centralize]{centralize()}} for a summary of graph centralization.
}
\examples{
# 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
