igraph (version 1.2.7)

difference.igraph.es: Difference of edge sequences

Description

Difference of edge sequences

Usage

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

Arguments

big

The ‘big’ edge sequence.

small

The ‘small’ edge sequence.

...

Ignored, included for S3 signature compatibility.

Value

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

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.
