R: Difference of edge sequences

difference.igraph.es {igraph} | R Documentation

## Difference of edge sequences

### Description

Difference of edge sequences

### Usage

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

### Arguments

`big` | The ‘big’ edge sequence.
`small` | The ‘small’ edge 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 edges is lost in the result.

### Value

An edge sequence that contains only edges that are part of `big`, but not part of `small`.
