IndexEdgeTaggedGraph
sets tags of edges in the graph g to their edge indices.
IndexEdgeTaggedGraph[g,r]
sets tags of edges to r,r+1,…
Details and Options

- IndexEdgeTaggedGraph is typically used to set unique tags for all edges in a graph.
- By default, the tags used for edges are integers starting at 1. Existing tags are overwritten.
- IndexEdgeTaggedGraph works with directed graphs, undirected graphs, multigraphs and mixed graphs.
- IndexEdgeTaggedGraph supports the same options as Graph.
