\title{Generate coordinates to place the vertices of a graph in a star-shape}
\usage{
layout_as_star(graph, center = V(graph)[1], order = NULL)
as_star(...)
}
\arguments{
\item{graph}{The graph to layout.}
\item{center}{The id of the vertex to put in the center. By default it is
the first vertex.}
\item{order}{Numeric vector, the order of the vertices along the perimeter.
The default ordering is given by the vertex ids.}
\item{...}{Arguments to pass to \code{layout_as_star}.}
}
\value{
A matrix with two columns and as many rows as the number of vertices
in the input graph.
}
\description{
A simple layout generator, that places one vertex in the center of a circle
and the rest of the vertices equidistantly on the perimeter.
}
\details{
It is possible to choose the vertex that will be in the center, and the
order of the vertices can be also given.
}
\examples{
g <- make_star(10)
layout_as_star(g)
## Alternative form
layout_(g, as_star())
}
