Intersection of vertex sequences
## S3 method for class 'igraph.vs'
intersection(...)
... |
The vertex sequences to take the intersection of. |
They must belong to the same graph. Note that this function has ‘set’ semantics and the multiplicity of vertices is lost in the result.
A vertex sequence that contains vertices that appear in all given sequences, each vertex exactly once.
