_D_e_s_c_r_i_p_t_i_o_n_:

     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_a_l_u_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.
