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.
