\usage{
array(x, dim=length(x), dimnames=NULL)

as.array(x)
is.array(x)
}
\alias{array}
\alias{as.array}
\alias{is.array}
\value{
An array with the extents specified in \code{dim}
and naming information in \code{dimnames}.
The values in \code{x} are taken to be those in the array with the
leftmost subscript moving fastest.  If there are too few elements
in \code{x} to fill the array, then the elements in \code{x} are
recycled.

\code{as.array()} coerces its argument to be an array by attaching a
\code{\link{dim}} attribute to it.  It also attaches \code{\link{dimnames}} if
\code{x} has \code{\link{names}}}. The sole purpose of this is to make it
possible to access the \code{dim}[names] attribute at a later time.

\code{is.array} returns \code{TRUE} or \code{FALSE} depending on
whether its argument is an array (i.e. has a \code{dim} attribute)
or not.
