| reverse_edges {igraph} | R Documentation |
Reverse edges in a graph
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 eids argument will be reversed. When reversing
all edges, this operation is also known as graph transpose.
Usage
reverse_edges(graph, eids = E(graph))
## S3 method for class 'igraph'
t(x)
Arguments
graph |
The input graph. |
eids |
The edge IDs of the edges to reverse. |
x |
The input graph. |
Value
The result graph where the direction of the edges with the given IDs are reversed
