\title{Reverse edges in a graph}
\usage{
reverse_edges(graph, eids = E(graph))
\method{t}{igraph}(x)
}
\arguments{
\item{graph}{The input graph.}
\item{eids}{The edge IDs of the edges to reverse.}
\item{x}{The input graph.}
}
\value{
The result graph where the direction of the edges with the given
IDs are reversed
}
\description{
The new graph will contain the same vertices, edges and attributes as
the original graph, except that the direction of the edges selected by
their edge IDs in the \code{eids} argument will be reversed. When reversing
all edges, this operation is also known as graph transpose.
}
\examples{
g <- make_graph(~ 1 -+ 2, 2 -+ 3, 3 -+ 4)
reverse_edges(g, 2)
