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