Difference of vertex sequences

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

`big` |
The ‘big’ vertex sequence. |

`small` |
The ‘small’ vertex sequence. |

`...` |
Ignored, included for S3 signature compatibility. |

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 only vertices that are part of
`big`

, but not part of `small`

.
