        The annual yield of wheat in a marginal wheat growing
        district on the Yorke Peninsula, South Australia,
        together with the rainfall for the three growing
        months, for the years 1931-1955.  The year itself is
        potentially a surrogate predictor to allow for improve-
        ments in varieties and farm practice.

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

        The data frame contains the following components:

       Year: Year of measurement

      Rain0: Rainfall for first growing month, in inches.

      Rain1: Rainfall for second growing month, in inches.

      Rain2: Rainfall for third growing month, in inches.

      Yield: Yield of wheat, in bushels per acre.
