I think that 'pch' is passed only to the panel function, and the key uses whatever the current trellis.par.set() is, if you don't define it explicitly (all explained in ?xyplot). I find it easier to call trellis.par.set before the xyplot:

R> trellis.par.set(superpose.symbol=list(pch=c(1, 2))) Warning message:
Note: The default device has been opened to honour attempt to modify trellis settings in: trellis.par.set(superpose.symbol = list(pch = c(1, 2))) R> xyplot(csoa~it|sex*agegp,data=tinting,groups=target,auto.key=list(space="right"))
