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

     A collection and description of functions which are useful
     utilities and tools used by Rmetrics. 

     The plot utility functions are:

       'characterTable'  Table of Numerical Equivalents to Latin Characters,
       'symbolTable'     Table of plot characters, plot symbols,
       'colorTable'      Table of Color Codes and Plot Colors itself,
       'greyPalette'     Creates a grey palette like rainbow does for colors.

     The tailored plot functions are:

       'histPlot'     Returns a tailored histogram plot,
       'densityPlot'  Returns a tailored kernel density estimate plot,
       'qqbayesPlot'  Returns a tailored quantile-quantile plot.

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

      
     characterTable(font = 1, cex = 0.7)
     symbolTable(font = par('font'), cex = 0.7)
     colorTable(cex = 0.7)
     greyPalette(n = 64, start = 255-n, end = 255)

     histPlot(x, col = "steelblue", border = "white", main = x@units, add.fit = TRUE, ...) 
     densityPlot(x, col = "steelblue", main = x@units, add.fit = TRUE, ...)
     qqbayesPlot(x, labels = TRUE, ...) 

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

 add.fit: [*Plot] - 
           a logical, should a fit added to the Plot? 

col, border, main: [*Plot] - 
           plot parameters. 

font, cex: [*table] - 
           an integer value, the number of the 'font', by default font 
          number 1, the standard font for the 'characterTable' or the
          current plot character font for the  'plotcharacterTable'.
          The character size is determined by the numeric value 'cex',
          the default size is 0.7. 

  labels: a logical, should labels be added to the plot? 

n, start, end: [greyPal] - cr 'n' gives the number of greys to be
          constructed, 'start' and 'end' span the range of the color
          palette. By default 64 grey tones equidistant chosen from the
          color range  (191, 191, 191) to (255, 255, 255). 

       x: an object of class '"timeSeries"'. 

     ...: optional arguments to be passed. 

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

     'characterTable' 
      displays a table with the characters of the requested font. The
     character on line "xy" and column "z" of the table has  code
     '"\xyz"', e.g 'cat("\126")' prints: V for font  number 1. These
     codes can be used as any other characters. 


     'symbolTable' 
      displays a table with the plot characters numbered from 0 to 255. 

     'colorTable' 
      displays a table with the plot colors with the associated color
     number.
