Let's extend the last example from the help to coplot():

 data(state)
 attach(data.frame(state.x77))
 coplot(Life.Exp ~ Income | Illiteracy * state.region, number = 3,
   panel = function(x, y, ...) {points(x, y, ...); abline(lm(y~x))})
 detach()

So just change the function for the argument 'panel'.
