Difference of edge sequences — difference.igraph.es • igraph

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.

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.
