IndexEdgeTaggedGraph

IndexEdgeTaggedGraph[g]

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 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.
