_D_e_s_c_r_i_p_t_i_o_n:

     Creates the banner of a 'mona' object.

_U_s_a_g_e:

     ## S3 method for class 'mona':
     plot(x, main = paste("Banner of ", deparse(x$call)),
               sub = NULL, xlab = "Separation step",
               col = c(2,0), axes = TRUE, adj = 0,
               nmax.lab = 35, max.strlen = 5, ...)

_A_r_g_u_m_e_n_t_s:

       x: an object of class '"mona"', typically created by 'mona(.)'.

main,sub: main and sub titles for the plot, with convenient defaults. 
          See documentation in 'plot.default'.

    xlab: x axis label, see 'title'.

 col,adj: graphical parameters passed to 'bannerplot()'.

    axes: logical, indicating if (labeled) axes should be drawn.

nmax.lab: integer indicating the number of labels which is considered
          too large for labeling.

max.strlen: positive integer giving the length to which strings are
          truncated in labeling.

     ...: further graphical arguments are passed to 'bannerplot()' and
          'text'.

_D_e_t_a_i_l_s:

     Plots the separation step at which clusters are splitted.  The
     observations are given in the order found by the 'mona' algorithm,
     the numbers in the 'step' vector are represented as bars between
     the observations.

     When a long bar is drawn between two observations, those
     observations have the same value for each variable. See chapter 7
     of Kaufman and Rousseeuw (1990).

_S_i_d_e _E_f_f_e_c_t_s:

     A banner is plotted on the current graphics device.

_N_o_t_e:

     In the banner plot, observation labels are only printed when the
     number of observations is limited less than 'nmax.lab' (35, by
     default), for readability. Moreover, observation labels are
     truncated to maximally 'max.strlen' (5) characters.

_R_e_f_e_r_e_n_c_e_s:

     see those in 'plot.agnes'.

_S_e_e _A_l_s_o:

     'mona', 'mona.object', 'par'.
