\title{Place nodes on a line or circle}
\usage{
layout_tbl_graph_linear(
graph,
circular,
sort.by = NULL,
use.numeric = FALSE,
offset = pi/2,
weight = NULL
)
}
\arguments{
\item{graph}{An \code{tbl_graph} object}
\item{circular}{Logical. Should the layout be transformed to a circular
representation. Defaults to \code{FALSE}.}
\item{sort.by}{The name of a node variable to sort the nodes by.}
\item{use.numeric}{Logical. Should a numeric sort.by attribute be used as the
actual x-coordinates in the layout. May lead to overlapping nodes. Defaults
to FALSE}
\item{offset}{If \code{circular = TRUE}, where should it begin. Defaults to
\code{pi/2} which is equivalent to 12 o'clock.}
\item{weight}{A weight for each node. Nodes will be spread out according to
their weight so that nodes with heigher weight will have more space around
them. Ignored if \code{use.numeric = TRUE}}
}
\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.
Further, if \code{circular = FALSE} a \code{width} column and if \code{circular = TRUE} a
\code{start}, \code{end}, and \code{r0} column.
}
\description{
This layout puts all nodes on a line, possibly sorted by a node attribute. If
\code{circular = TRUE} the nodes will be laid out on the unit circle instead.
In the case where the \code{sort.by} attribute is numeric, the numeric values
will be used as the x-position and it is thus possible to have uneven spacing
between the nodes.
