union.igraph.vs {igraph} | R Documentation |
Union of vertex sequences
Description
Union of vertex sequences
Usage
## S3 method for class 'igraph.vs'
union(...)
Arguments
... |
The vertex sequences to take the union of. |
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. (This is to match the behavior of the based unique
function.)
Value
A vertex sequence that contains all vertices in the given sequences, exactly once.
