Difference of vertex sequences
# S3 method for igraph.vs
difference(big, small, ...)
A vertex sequence that contains only vertices that are part of
big, but not part of 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
Other vertex and edge sequence operations:
g <- make_(ring(10), with_vertex_(name = LETTERS[1:10]))
