	_A_r_g_u_m_e_n_t_s:
	
	           x : a vector of values for which the histogram is
	               desired.
	
	      breaks : either a single number giving the approximate
	               number of cells for the histogram or a vector
	               giving the breakpoints between histogram
	               cells.
	
	        freq : a logical vector which indicates whether the
	               histogram is to present a representation of
	               frequencies (the default) or relative fre-
	               quencies.
	
	         col : a colour to be used to fill draw the bars.
	               The default of NULL yields unfilled bars.
	
	      border : the color of the border around the bars.
	
	         ... : graphical parameters can also be specified as
	               arguments.
	
	_D_e_s_c_r_i_p_t_i_o_n:
	
	     hist computes and plots a histogram of the given data
	     values.  The histogram cells are intervals of the form
	     [a,b), i.e. they include their left-hand endpoint, but
	     not their right one.
