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

       x: Variable for x axis. 

       x: Variable for y axis. 

       f: Factor (or variable for which as.factor() works). 

    data: data frame for variables x, y, f. Default: sys.parent(). 

     col: Color numbers to use in plot. Will be replicated if shorter
          than the number of levels of the factor f. Default: 1:10. 

     pch: Vector of plot characters. Replicated if necessary. Default:
          "O". 

     add: If TRUE, add to existing plot. Otherwise, create new plot.
