\title{Load a graph from the graph database for testing graph isomorphism.}
\usage{
graph.graphdb(
  url = NULL,
  prefix = "iso",
  type = "r001",
  nodes = NULL,
  pair = "A",
  which = 0,
  base = "http://cneurocvs.rmki.kfki.hu/graphdb/gzip",
  compressed = TRUE,
  directed = TRUE
)
}
\arguments{
\item{url}{If not \code{NULL} it is a complete URL with the file to import.}

\item{prefix}{Gives the prefix. See details below. Possible values:
\code{iso}, \code{i2}, \code{si4}, \code{si6}, \code{mcs10}, \code{mcs30},
\code{mcs50}, \code{mcs70}, \code{mcs90}.}

\item{type}{Gives the graph type identifier. See details below. Possible
values: \code{r001}, \code{r005}, \code{r01}, \code{r02}, \code{m2D},
\code{m2Dr2}, \code{m2Dr4}, \code{m2Dr6} \code{m3D}, \code{m3Dr2},
\code{m3Dr4}, \code{m3Dr6}, \code{m4D}, \code{m4Dr2}, \code{m4Dr4},
\code{m4Dr6}, \code{b03}, \code{b03m}, \code{b06}, \code{b06m}, \code{b09},
\code{b09m}.}

\item{nodes}{The number of vertices in the graph.}

\item{pair}{Specifies which graph of the pair to read. Possible values:
\code{A} and \code{B}.}

\item{which}{Gives the number of the graph to read. For every graph type
there are a number of actual graphs in the database. This argument specifies
which one to read.}

\item{base}{The base address of the database. See details below.}

\item{compressed}{Logical constant, if TRUE than the file is expected to be
compressed by gzip. If \code{url} is \code{NULL} then a \sQuote{\code{.gz}}
suffix is added to the filename.}

\item{directed}{Logical constant, whether to create a directed graph.}

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