\title{The Sugiyama graph layout generator}
\usage{
layout.sugiyama(
graph,
layers = NULL,
hgap = 1,
vgap = 1,
maxiter = 100,
weights = NULL,
attributes = c("default", "all", "none")
)
}
\arguments{
\item{graph}{The input graph.}
\item{layers}{A numeric vector or \code{NULL}. If not \code{NULL}, then it
should specify the layer index of the vertices. Layers are numbered from
one. If \code{NULL}, then igraph calculates the layers automatically.}
\item{hgap}{Real scalar, the minimum horizontal gap between vertices in the
same layer.}
\item{vgap}{Real scalar, the distance between layers.}
\item{maxiter}{Integer scalar, the maximum number of iterations in the
crossing minimization stage. 100 is a reasonable default; if you feel that
you have too many edge crossings, increase this.}
\item{weights}{Optional edge weight vector. If \code{NULL}, then the
'weight' edge attribute is used, if there is one. Supply \code{NA} here and
igraph ignores the edge weights. These are used only if the graph
contains cycles; igraph will tend to reverse edges with smaller weights
when breaking the cycles.}
\item{attributes}{Which graph/vertex/edge attributes to keep in the extended
graph. \sQuote{default} keeps the \sQuote{size}, \sQuote{size2},
\sQuote{shape}, \sQuote{label} and \sQuote{color} vertex attributes and the
\sQuote{arrow.mode} and \sQuote{arrow.size} edge attributes. \sQuote{all}
keep all graph, vertex and edge attributes, \sQuote{none} keeps none of
them.}

\code{layout.sugiyama()} was renamed to \code{layout_with_sugiyama()} to create a more
consistent API.
