Dear R group

I am making multiple xyplot, and would like to have tick marks on bottom and left in EACH panel, but only tick labels at the bottom and left of the whole graph.
I have browsed the internet, as well as the help page without success.
If anyone could help me find the path to the solution I would appreciate.
Here is an example, this is the best I could do:

x.data <- rnorm(16,20,7);y.data <- rnorm(16,.55,.25); z.data <- sample(1:4,16,replace=T)
xyplot(y.data~x.data|z.data, layout=c(2,2),
