_D_e_s_c_r_i_p_t_i_o_n:

     Sums of squares between and within the columns of a matrix. Allows
     for missing values. This function is called by the 'anova' method
     for 'MAList' objects.

_U_s_a_g_e:

     bwss.matrix(x)

_A_r_g_u_m_e_n_t_s:

       x: a numeric matrix.

_D_e_t_a_i_l_s:

     This is equivalent to a one-way analysis of variance where the
     columns of the matrix are the groups. If 'x' is a matrix then
     'bwss.matrix(x)' is the same as 'bwss(x,col(x))' except for speed
     of execution.

_V_a_l_u_e:

     A list with components 

     bss: sums of squares between the column means.

     wss: sums of squares within the column means.

     bdf: degrees of freedom corresponding to 'bss'.

     wdf: degrees of freedom corresponding to 'wss'.
