\title{Convert igraph graphs to graphNEL objects from the graph package}
\usage{
as_graphnel(graph)
}
\arguments{
\item{graph}{An igraph graph object.}
}
\value{
\code{as_graphnel()} returns a graphNEL graph object.
}
\description{
The graphNEL class is defined in the \code{graph} package, it is another
way to represent graphs. These functions are provided to convert between
the igraph and the graphNEL objects.
}
\details{
\code{as_graphnel()} converts an igraph graph to a graphNEL graph. It
converts all graph/vertex/edge attributes. If the igraph graph has a
vertex attribute \sQuote{\code{name}}, then it will be used to assign
vertex names in the graphNEL graph. Otherwise numeric igraph vertex ids
will be used for this purpose.
