Sebastian -
panel.loess will be more suitable for use with
xyplot. To get both points and the smoothed line,
you can use
xyplot(incidence~year,melanoma,panel=function(x,y,...){
panel.xyplot(x,y,...)
panel.loess(x,y,...)})

Hi,
The following call:
xyplot(incidence ~ year, melanoma, panel=panel.smooth)
produces a blank plot region with an error message:

Is this a known problem with the above environment?
