[R] Help on PLotting

We were wondering if there was a simple way to plot two series, say y and 
z, against a series x and have both series appear in the same plot. 

For example the function plot(x~y+z) generates two scatter plots, one with
y against x and the other with z against x. Is there any way to obtain
both on the same picture?  

Thanks for your help
