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

     This plot shows the relative proportions of three variables in one
     diagramm. It is important that the proportion sum up to 100% and
     if the values of the variables are very different it is important
     to scale them to the same data range.

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

     ternary(x, nam = NULL, grid = FALSE, ...)

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

       x: matrix with 3 columns 

     nam: names of the variables 

    grid: if TRUE the grid should be plotted 

     ...: further graphical parameters, see par 

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

     The relative proportion of each variable is computed and those
     points are plotted into the graphic.
