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

     Off-diagonal panel functions for 'pairs.table'.

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

     pairs_strucplot(panel = mosaic, 
       type = c("pairwise", "total", "conditional", "joint"),
       legend = FALSE, margins = c(0, 0, 0, 0), labeling = NULL, ...)
     pairs_assoc(...)
     pairs_mosaic(...)
     pairs_sieve(...)

_A_r_g_u_m_e_n_t_s:

   panel: function to be used for the plots in each cell, such as
          'pairs_assoc', 'pairs_mosaic', and 'pairs_sieve'.

    type: character string specifying the type of independence model
          visualized in the cells.

  legend: logical specifying whether a legend should be displayed in
          the cells or not.

 margins: margins inside each cell (see 'strucplot').

labeling: labeling function or labeling-generating function (see
          'strucplot').

     ...: 'pairs_mosaic', 'pairs_assoc', and 'pairs_sieve': parameters
          passed to 'pairs_strucplot'. 'pairs_strucplot': other
          parameters passed to panel function.

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

     These functions really just wrap 'assoc', 'sieve', and 'mosaic' by
     basically inhibiting labeling and legend-drawing and setting the
     margins to 0.

_V_a_l_u_e:

     A function with arguments: 

       x: contingency table.

     i,j: cell coordiantes.
