Intersection of edge sequences
Usage
# S3 method for class 'igraph.es'
intersection(...)Value
An edge sequence that contains edges that appear in all given sequences, each edge exactly once.
Details
They must belong to the same graph. Note that this function has ‘set’ semantics and the multiplicity of edges is lost in the result.
