R: Difference of vertex sequences

difference.igraph.vs {igraph} | R Documentation

## Difference of vertex sequences

### Description

Difference of vertex sequences

### Usage

    ## S3 method for class 'igraph.vs'
    difference(big, small, ...)

### Arguments

`big` | The ‘big’ vertex sequence.
`small` | The ‘small’ vertex sequence.
`...` | Ignored, included for S3 signature compatibility.

### 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 only vertices that are part of `big`, but not part of `small`.
