\title{Chordality of a graph}
\usage{
is.chordal(
  graph,
  alpha = NULL,
  alpham1 = NULL,
  fillin = FALSE,
  newgraph = FALSE
)
}
\arguments{
\item{graph}{The input graph. It may be directed, but edge directions are
ignored, as the algorithm is defined for undirected graphs.}

\item{alpha}{Numeric vector, the maximal chardinality ordering of the
vertices. If it is \code{NULL}, then it is automatically calculated by
calling \code{\link[=max_cardinality]{max_cardinality()}}, or from \code{alpham1} if
that is given..}

\item{alpham1}{Numeric vector, the inverse of \code{alpha}. If it is
\code{NULL}, then it is automatically calculated by calling
\code{\link[=max_cardinality]{max_cardinality()}}, or from \code{alpha}.}

\item{fillin}{Logical scalar, whether to calculate the fill-in edges.}

\item{newgraph}{Logical scalar, whether to calculate the triangulated graph.}

\code{is.chordal()} was renamed to \code{\link[=is_chordal]{is_chordal()}} to create a more
consistent API.
