        An experiment involving barley and manure (nitrogen)
        was conducted in 6 blocks of 3 whole plots.

   DDeettaaiillss::

        Each whole plot was divided into 4 subplots.  Three
        varieties of barley were used in the experiment with
        one variety being sown in each whole plot, while the
        four levels of manure (0, 0.01, 0.02, and 0.04 tons per
        acre) were used, one level in each of the four subplots
        of each whole plot.

        The `barley' object is a data frame of four components:

          B: The block, as a factor with levels `B1', `B2'
             ...{} `B6'

          V: Barley varieties, as a factor with levels `V1'
             `V2' `V3'

          N: Nitrogen applied, in hundredths of tons per acre.

          Y: Yield or barley
