Hi

Does this do what you want ?

library(latticeExtra)
c(vol_p, xy_p, x.same=TRUE)

Thanks, Bert.

I have used latticeExtra for layering graphics.  I'm not sure how I
would use it to align graphics rather superimposing them.

I shall look into the the custom panel plot but that is very new
territory for me.

Write a custom panel function for levelplot() that calls
panel.xyplot after panel.levelplot. I believe this can also be done
by the +  operator of the latticeExtra package.

You do *not* want to call xyplot after levelplot, as that
completely redraws the plot.

Cheers, Bert

I am drawing a levelplot and an xyplot on a single device as shown
in the runnable example below.  I would like the x axes to align -
that is for them to cover the same extent left-to-right on the
device. How do I go about doing that?

####### # START ####### library(lattice)

d <- dim(volcano) xy <- data.frame(x = 1:d[1], y = volcano[,30] )

vol_p <- levelplot(volcano) xy_p <- xyplot(y ~ x, data = xy)

print(vol_p, split = c(1, 2, 1, 2), more = TRUE) print(xy_p,  split
= c(1, 1, 1, 2), more = FALSE) ###### #END ######


Thanks! Ben
