Hi, Michael,

Use the skip argument.

library(lattice)
z <- expand.grid(x = 1:10, y = 1:10, p = 1:5)
z$p <- factor(z$p, levels = c(1, 5, 2, 4, 3))
xyplot(y ~ x | p, z, layout = c(2, 3),
        skip = c(FALSE, FALSE, FALSE, FALSE, TRUE, FALSE))


Also you are using xYplot (presumably from Hmisc) and not lattice::xyplot.

Thanks,
