	     barplot(height, names.arg, col, border=par("fg"),
	             beside=FALSE, space=0.2, legend.text,
	             main=NULL, xlab=NULL, ylab=NULL,
	             xlim, ylim)
	
	_A_r_g_u_m_e_n_t_s:
	
	      height : either a vector or matrix of values descibing
	               the the bars which make up the plot.  If
	               height is a vector, the plot consists of a
	               sequence of rectangular bars with heights
	               given by the values in the vector.  If height
	               is a matrix and beside is FALSE then each bar
	               of the plot corresponds to a column of
	               height, with the values in the column giving
	               the heights of stacked ``sub-bars'' making up
	               the bar.  If height is a matrix and beside is
	               TRUE, then the values in each column are jux-
	               taposed rather than stacked.
	
	   names.arg : a vector of names to be plotted below each
	               bar or group of bars.  If this argument is
	               omitted, then the names are taken from the
	               names attribute of height if height is a vec-
	               tor, or the column names of height if height
	               is a matrix.
	
	         col : a vector of colors for the bars or bar com-
	               ponents.
	
	      border : The color to be used for the border of the
	               bars.
	
	      beside : a logical value.  If FALSE, the columns of
	               height are portrayed as stacked bars, and if
	               TRUE the columns are portrayed as juxtaposed
	               bars.
	
	       space : the relative amount of space between the bars
	               or groups of bars. The width of a bar (or
	               group of bars) plus the value of space is
	               one.
	
	 legend.text : a vector of text used to construct a legend
	               for the plot.  This is only useful when
	               height is a matrix.  In that case the legend
	               labels should correspond to the rows of
	               height.
	
	        main : an overall title for the plot.
	
	        xlab : a label for the x axis.
	
	        ylab : a label for the y axis.
	
	        xlim : limits for the x axis.
	
	        ylim : limits for the y axis.
	
	_V_a_l_u_e:
	
	     This function is invoked for its side effect of produc-
	     ing a barplot in the graphics window.  It returns no
	     useful value.
	
	_S_e_e _A_l_s_o:
	
	     dotplot, hist.
	
	_E_x_a_m_p_l_e_s:
	
	     data(deaths)
	     barplot(deaths, beside=TRUE,
	             col=c("lightblue", "mistyrose", "lightcyan",
	                   "lavender", "cornsilk"),
	             legend=rownames(deaths), ylim=c(0,100))
	     title(main="Death Rates in Virginia", font.main=4)
	
	     barplot(t(deaths)[,5:1], beside=TRUE,
	             col=c("lightblue", "mistyrose",
	                   "lightcyan", "lavender"),
	             legend=colnames(deaths), ylim=c(0,80))
	     title(main="Death Rates in Virginia", font.main=4)
