_F_o_r_m_a_t_:

     A data frame with 12 observations on 2 variables:

      [ , 1]     `x'     numeric     per capita GNP
      [ , 2]     `y'     numeric     percentage in agriculture

     The row names of the data frame indicate the countries.

     The data seem to show two clusters, the ``more agricul-
