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

     8 characteristics for 18 popular flowers.

_U_s_a_g_e:

     data(flower)

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

     A data frame with 18 observations on 8 variables:

       [ , 1]  factor   winters
       [ , 2]  factor   shadow
       [ , 3]  factor   tubers
       [ , 4]  factor   color
       [ , 5]  ordered  soil
       [ , 6]  ordered  preference
       [ , 7]  numeric  height
       [ , 8]  numeric  distance

     _w_i_n_t_e_r_s is binary and indicates whether the plant may be left in
          the garden when it freezes.

     _s_h_a_d_o_w is binary and shows whether the plant needs to stand in the
          shadow.

     _t_u_b_e_r_s is asymmetric binary and distinguishes between plants with
          tubers and plants that grow in any other way.

     _c_o_l_o_r is nominal and specifies the flower's color (1 = white, 2 =
          yellow, 3 = pink, 4 = red, 5 = blue).

     _s_o_i_l is ordinal and indicates whether the plant grows in dry (1),
          normal (2), or wet (3) soil.

     _p_r_e_f_e_r_e_n_c_e is ordinal and gives someone's preference ranking going
          from 1 to 18.

     _h_e_i_g_h_t is interval scaled, the plant's height in centimeters.

     _d_i_s_t_a_n_c_e is interval scaled, the distance in centimeters that
          should be left between the plants.
