reverse_edges {igraph} | R Documentation |
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 eids
argument will be reversed. When reversing
all edges, this operation is also known as graph transpose.
reverse_edges(graph, eids = E(graph))
