R: Intersection of vertex sequences

intersection.igraph.vs {igraph} | R Documentation

## Intersection of vertex sequences

### Description

Intersection of vertex sequences

### Usage

    ## S3 method for class 'igraph.vs'
    intersection(...)

### Arguments

`...` | The vertex sequences to take the intersection of.

### Details

They must belong to the same graph. Note that this function has ‘set’ semantics and the multiplicity of vertices is lost in the result.

### Value

A vertex sequence that contains vertices that appear in all given sequences, each vertex exactly once.
