get_multiedge_count {DiagrammeR} | R Documentation |
Get a count of the number of mutiple
edges in the graph. Included in the count is the
number of separate edges that share the same edge
definition (i.e., same pair of nodes) across the
entire graph. So, for example, if there are 2
edge definitions in the graph that involve 6
separate edge IDs, the count will be 4
.
