\title{Incident edges of a vertex in a graph}
\usage{
incident(graph, v, mode = c("all", "out", "in", "total"))
}
\arguments{
\item{graph}{The input graph.}

\item{v}{The vertex of which the incident edges are queried.}

\item{mode}{Whether to query outgoing (\sQuote{out}), incoming
(\sQuote{in}) edges, or both types (\sQuote{all}). This is
ignored for undirected graphs.}
}
\value{
An edge sequence containing the incident edges of
the input vertex.
}
\description{
Incident edges of a vertex in a graph
