   VVaalluuee::

        This function creates a integer vector of the specified
        length.  Each element of the vector is equal to `0'.
        Integer vectors exist so that data can be passed to C
        or Fortran code which expects them.

        `as.integer' attempts to coerce its argument to be of
        integer type.

        `is.integer' returns `TRUE' or `FALSE' depending on
        whether its argument is of integer type or not.
