Hi Uwe,

I am aware of the "legend" option in xyplot, but I can't figure out how to make it work. In particular, I do not understand how to use "legend" along with the "key" argument. For my example, I would like to have a legend box inside the plotting frame to indicate the 3 different smoothed curves. Can someone give me a simple example or show how to do this for my example?

Thanks very much,

Ravi.
