[R] lattice/xyplot: plotting 4 variables in two panels - can this be done?

[Gabor Grothendieck]

Try xyplot.zoo in the zoo package (be sure you have
the latest zoo version). One caveat is that xyplot.zoo is
under development and could change.  Here we use the
builtin data set anscombe as an example:

# display the anscombe data set
anscombe

library(lattice)
library(zoo)
# create zoo object using column 1 as x/times and columns 5:8 as the y's
z <- zoo(data.matrix(anscombe[,5:8]), anscombe[,1])
xyplot(z, screens = c(1, 1, 2, 2), col = 1:4, pch = 1:4, type = "b")

Thus if there are 3 subjects I should end up with 6 panels. Is there a simple way of doing so (i.e. without calling xyplot() several times, and then padding the results together)??
