\title{Select vertices and show their metadata}
\usage{
\method{[[}{igraph.vs}(x, ...)
}
\arguments{
\item{x}{A vertex sequence.}
\item{...}{Additional arguments, passed to \code{[}.}
}
\value{
The double bracket operator returns another vertex sequence,
with meta-data (attribute) printing turned on. See details below.
}
\description{
The double bracket operator can be used on vertex sequences, to print
the meta-data (vertex attributes) of the vertices in the sequence.
}
\details{
Technically, when used with vertex sequences, the double bracket
operator does exactly the same as the single bracket operator,
but the resulting vertex sequence is printed differently: all
attributes of the vertices in the sequence are printed as well.
See \code{\link{[.igraph.vs}} for more about indexing vertex sequences.

\examples{
g <- make_ring(10) \%>\%
set_vertex_attr("color", value = "red") \%>\%
set_vertex_attr("name", value = LETTERS[1:10])
V(g)
V(g)[[]]
V(g)[1:5]
V(g)[[1:5]]
