\alias{layout_tbl_graph_eigen}
\title{Place nodes according to their eigenvalues}
\usage{
layout_tbl_graph_eigen(
graph,
type = "laplacian",
eigenvector = "smallest",
circular = FALSE
)
}
\arguments{
\item{graph}{A tbl_graph object}
\item{type}{The type of matrix to extract the eigenvectors from. Either
\code{'laplacian'} or \code{'adjacency'}}
\item{eigenvector}{The eigenvector to use for coordinates. Either \code{'smallest'}
or \code{'largest'}}
\item{circular}{ignored}
}
\value{
A data.frame with the columns \code{x}, \code{y}, \code{circular} as
well as any information stored as node variables in the tbl_graph object.
}
\description{
This layout is based on the idea of spectral layouts where node coordinates
are calculated directly by decomposing a matrix representation of the graph
and extracting the eigenvectors.
