_D_e_s_c_r_i_p_t_i_o_n:

     Use 'ternarypoints' to add points to a ternary diagram generated
     using the 'ternaryplot' function in the vcd library.  Use ternary
     diagrams to plot expected values for multinomial choice models
     with three categories in the dependent variable.

_U_s_a_g_e:

     ternarypoints(object, pch = 19, col = "blue", ...)

_A_r_g_u_m_e_n_t_s:

  object: The input object must be a matrix with three columns. 

     pch: The selected type of point.  By default, 'pch = 19', solid
          disks. 

     col: The color of the points.  By default, 'col = "blue"'. 

     ...: Additional parameters passed to 'points'. 

_V_a_l_u_e:

     The 'ternarypoints' command adds points to a previously existing
     ternary diagram.  Use 'ternaryplot' in the 'vcd' library to
     generate the main ternary diagram.
