vertex_attr<-
Set one or more vertex attributes
Set one or more vertex attributes
Usage
vertex_attr(graph, name, index = V(graph)) <- valueArguments
- graph
The graph.
- name
The name of the vertex attribute to set. If missing, then
valuemust be a named list, and its entries are set as vertex attributes.- index
An optional vertex sequence to set the attributes of a subset of vertices.
- value
The new value of the attribute(s) for all (or
index) vertices.
Value
The graph, with the vertex attribute(s) added or set.
