Permute the vertices of a graph
Create a new graph, by permuting vertex ids.
permute(graph, permutation)
graph |
The input graph, it can directed or undirected. |
permutation |
A numeric vector giving the permutation to apply. The
first element is the new id of vertex 1, etc. Every number between one and

This function creates a new graph from the input graph by permuting its
vertices according to the specified mapping. Call this function with the
output of canonical_permutation to create the canonical form
of a graph.
permute keeps all graph, vertex and edge attributes of the graph.
A new graph object.
