[R] duplicate data points on a line graph

[NDC/jshipman]

Hi,
	I am new to R plot.  I am trying to increase the data point  
observation when duplicate data points exist

x	y
1	10
1	10
2	3
4	5
9 	8


in the about example  1, 10 would be displayed larger than the other  
data points.  Could someone give me some assistance with this problem
