Difference of vertex sequences
## S3 method for class 'igraph.vs' difference(big, small, ...)
The ‘big’ vertex sequence.
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
Other vertex and edge sequence operations:
g <- make_(ring(10), with_vertex_(name = LETTERS[1:10])) difference(V(g), V(g)[6:10])
