   VVaalluuee::

        An array with the extents specified in `dim' and naming
        information in `dimnames'.  The values in `x' are taken
        to be those in the array with the leftmost subscript
        moving fastest.  If there are too few elements in `x'
        to fill the array, then the elements in `x' are recy-
        cled.

        `as.array' coerces its argument to be an array by
        attaching a `dim' attribute to it.  The sole purpose of
        this is to make it possible to access the `dim'
        attribute at a later time.

        `is.array' returns `TRUE' or `FALSE' depending on
        whether its argument is an array (i.e. has a `dim'
        attribute) or not.
