Dear David,
do you know how to get plotmath-like symbols in both rows?
I tried s.th. like:
lab<- expression(paste(alpha==1, ", ", beta==2, sep=""))
xlab<- substitute(expression( atop(lab==lab., bold(foo)) ), list(lab.=lab))
xyplot(0 ~ 0, xlab = xlab)
Marius,
I always find paste a bit tricky with plotmath.
Maybe this will do what you want:
mylab <- expression( atop(lab==list(alpha==1, beta==2), bold(foo)) )
xyplot(0 ~ 0, xlab = mylab)

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)))
--
David.
Thanks!

Dear expeRts,
I recently asked for a real "centered" title (see, e.g.,
http://tolstoy.newcastle.edu.au/R/e13/help/11/01/0135.html).
A nice solution (from Deepayan Sarkar) is to use "xlab.top" instead of "main":
library(lattice)
trellis.device("pdf")
print(xyplot(0 ~ 0, xlab.top = "This title is now 'centered' for the human's eye", sub =
"but subtitles are not centered", scales = list(alternating = c(1,1), tck = c(1,0))))
dev.off()
library(lattice)
trellis.device("pdf")
print(xyplot(0 ~ 0, xlab.top = "This title is now 'centered' for the human's eye", xlab =
"but subtitles are _now_ centered", scales = list(alternating = c(1,1), tck = c(1,0))))
dev.off()
(I realize that those are not really subtitles by a 'lab', but that appears
acceptable in your current test case.)
My question is whether there is something similar for *sub*titles [so something like
"xlab.bottom"]? As you can see from the plot, the subtitle does not seem to be
"centered" for the human's eye. I would like to center it according to the x-axis label.
