Use packet.number() to identify which data subset you are dealing with
(inside the panel function):
xyplot(y~x|a,
panel=function(...){
panel.loess(...)
panel.text(0,2,label=c('best','better','bad','worst')[packet.number()])
})
There is also panel.number() which is similar but refers to the panel
position rather than data set. The difference shows up if you
re-arrange the panels from the default ordering.
