\usage{
read.graph(
  file,
  format = c("edgelist", "pajek", "ncol", "lgl", "graphml", "dimacs", "graphdb", "gml",
    "dl"),
  ...
)
}
\arguments{
\item{file}{The connection to read from. This can be a local file, or a
\code{http} or \code{ftp} connection. It can also be a character string with
the file name or URI.}

\item{format}{Character constant giving the file format. Right now
\code{edgelist}, \code{pajek}, \code{ncol}, \code{lgl}, \code{graphml},
\code{dimacs}, \code{graphdb}, \code{gml} and \code{dl} are supported,
the default is \code{edgelist}. As of igraph 0.4 this argument is case

\ifelse{html}{\href{https://lifecycle.r-lib.org/articles/stages.html#deprecated}{\figure{lifecycle-deprecated.svg}{options: alt='[Deprecated]'}}}{\strong{[Deprecated]}}

\code{read.graph()} was renamed to \code{\link[=read_graph]{read_graph()}} to create a more
consistent API.
