Dear David, I intended to use another x-label. But your suggestion brings me to the idea of just using a two-line xlab, so s.th. like print(xyplot(0 ~ 0, xlab.top = "This title is now 'centered' for the human's eye", xlab = "but subtitles are _now_ centered\nbla", scales = list(alternating = c(1,1), tck = c(1,0))))
And if you wanted different fontface (underline, italic or bold) then you could use plotmath expressions: xyplot(0 ~ 0, xlab.top = "This title is now 'centered' for the human's eye", xlab = expression( atop(but~subtitles2~are~underline(now)~centered, bold(bla) )), scales = list(alternating = c(1,1), tck = c(1,0)))
