Thank you for this response. But it looks like I poorly specified the problem. I only want to have a strip at the very top of the plot, not at the top of each panel.

You can probably understand why I want this better if we take your example and swap the givens around:

xyplot(mpg ~ disp | factor(cyl) * HP, mtcars,

par.strip.text = list(lines = 0.5), strip = function(which.given, which.panel, ...) { if (which.given == 1) strip.default(which.given = 1, which.panel = which.panel[which.given], ...) })

So now I have 4, 6, and 8 at the top of every row of panels as a label for cyl. But I don't need that--really I only need 4, 6, and 8 at the very top (or bottom) of the plot, just like with default settings I only get the axis labels at the top and bottom of the plot, not duplicated for every panel.

What I want is to draw strips at the very top of the plot and not to draw strips that are between panels.

Can this be done?
