Difference of vertex sequences

Usage

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

Arguments

big

The ‘big’ vertex sequence.

small

The ‘small’ vertex sequence.

...

Ignored, included for S3 signature compatibility.

Value

A vertex sequence that contains only vertices 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 vertices is lost in the result.

Examples

g <- make_(ring(10), with_vertex_(name = LETTERS[1:10]))
difference(V(g), V(g)[6:10])
#> + 5/10 vertices, named, from 740e33d:
#> [1] A B C D E
