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

     The data are from a foster feeding experiment with rat mothers and
     litters of four different genotypes. The measurement is the litter
     weight after a trial feeding period.

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

     data("foster")

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

     A data frame with 61 observations on the following 3 variables.

     '_l_i_t_g_e_n' genotype of the litter, a factor with levels  'A', 'B',
          'I', and 'J'.

     '_m_o_t_g_e_n' genotype of the mother, a factor with levels  'A', 'B',
          'I', and 'J'.

     '_w_e_i_g_h_t' the weight of the litter after a feeding period.

_D_e_t_a_i_l_s:

     Here the interest lies in uncovering the effect of genotype of
     mother and litter on  litter weight.
