\title{The size of the graph (number of edges)}
\usage{
gsize(graph)
ecount(graph)
}
\arguments{
\item{graph}{The graph.}
}
\value{
Numeric scalar, the number of edges.
}
\description{
\code{ecount()} and \code{gsize()} are aliases.
}
\examples{
g <- sample_gnp(100, 2 / 100)
gsize(g)
ecount(g)
# Number of edges in a G(n,p) graph
replicate(100, sample_gnp(10, 1 / 2), simplify = FALSE) \%>\%
vapply(gsize, 0) \%>\%
hist()
