\title{Set one or more vertex attributes}
\usage{
vertex_attr(graph, name, index = V(graph)) <- value
}
\arguments{
\item{graph}{The graph.}
\item{name}{The name of the vertex attribute to set. If missing,
then \code{value} must be a named list, and its entries are
set as vertex attributes.}
\item{index}{An optional vertex sequence to set the attributes
of a subset of vertices.}
\item{value}{The new value of the attribute(s) for all
(or \code{index}) vertices.}
}
\value{
The graph, with the vertex attribute(s) added or set.
}
\description{
Set one or more vertex attributes
}
\examples{
g <- make_ring(10)
vertex_attr(g) <- list(name = LETTERS[1:10],
color = rep("yellow", gorder(g)))
vertex_attr(g, "label") <- V(g)$name
g
plot(g)
