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.
