Intersection of vertex sequences
# S3 method for igraph.vs intersection(...)
A vertex sequence that contains vertices that appear in all given sequences, each vertex exactly once.
They must belong to the same graph. Note that this function has ‘set’ semantics and the multiplicity of vertices is lost in the result.
Other vertex and edge sequence operations:
g <- make_(ring(10), with_vertex_(name = LETTERS[1:10])) intersection(E(g)[1:6], E(g)[5:9]) #> + 2/10 edges from 9862e75 (vertex names): #>  E--F F--G
