\title{Create a star graph, a tree with n vertices and n - 1 leaves}
\usage{
make_star(n, mode = c("in", "out", "mutual", "undirected"), center = 1)
star(...)
}
\arguments{
\item{n}{Number of vertices.}
\item{mode}{It defines the direction of the
edges, \code{in}: the edges point \emph{to} the center, \code{out}:
the edges point \emph{from} the center, \code{mutual}: a directed
star is created with mutual edges, \code{undirected}: the edges
are undirected.}
\item{center}{ID of the center vertex.}
\item{...}{Passed to \code{make_star}.}
}
\value{
An igraph graph.
}
\description{
\code{star} creates a star graph, in this every single vertex is
connected to the center vertex and nobody else.
}
\examples{
make_star(10, mode = "out")
make_star(5, mode = "undirected")
