[R] xyplot - show values of a series on graph

[taz9]

Thank you very much for your help. I tried to use lattice but I'm not sure
how to restrict it to display only the values of "cars".

xyplot(cars+trucks~year, data=df2, type="o",
panel=function(x,y,...){
	panel.xyplot(x,y,...)
	grid.text(unit(x,"native"),unit(y,"native"),label=y, just="top")}
   )
