xyplot(y1 + y2 ~ x | z, data = data, outer = TRUE)
or to allow different y-axes and a common x-axis,
xyplot(y1 + y2 ~ x | z, data = data, outer = TRUE,
scales = list(y = list(relation = "free", rot = 0)))
There are of course many other customizations possible.
If you want a common y-axis for each row, but a different one for
different rows, that's a bit harder (though not impossible).
