Yes, the necessary space should be automatically allocated. Details of
version / device might help diagnosing the problem.

[R] Increasing space for main title in a lattice (xyplot()) graphics.

OK. Now for a tougher problem: how to make the first line bold font and the
second line normal font (and/or different colors)?

My reading of the docs did not reveal how to do it, but I found a way using
a textGrob for the title (i.e. main ). But it's tricky, as the "obvious
solution" of using different y values for the lines caused lattice to
enlarge the title viewport too much, shrinking the graph panels so that
details were lost. I think I have found a way to avoid this and make it
work, but I'll delay giving my somewhat clumsy "solution" until
some of you
have a chance to find a more sensible approach, if you care to try.

[R] Increasing space for main title in a lattice (xyplot()) graphics.

Hi Bert,

You are right that the general solution is for 'main' to be a (grid)
grob. It is not clear (to me) what the "height" of a textGrob with
multiple labels should be, but the following gives reasonable results:

xyplot(1 ~ 1,
       main = textGrob(c("The quick brown fox jumped", "over the
lazy dog"),
                       x = unit(0.5, "npc"), y = unit(c(0.75, 0.25),
"cm")))

I'm guessing your first attempt was with the default units ("npc")
for y.

The correct grob (allowing more detailed control) to use for complex
grid objects is a frameGrob.

lattice does have an interface to create (simple) frameGrobs, for
constructing legends. This can be (ab)used as follows:

xyplot(1 ~ 1,
       main = draw.key(key = list(text = list(c("The quick brown fox
jumped",
                                                "over the lazy dog"),
                                              font = c(1, 2), col = c(2, 3)))))

Aaaarrrgghhh!!! The diagnosis of the problem was, as usual, trivial.  It 
was all down to my overwhelming stupidity.  I put together the main 
title by pasting together various bits --- and FORGOT to include the 
very first bit, which was the first line of the two-line title.  (Smoke 
comes out of ears!!!)

Took me hours, with accompanying hair loss, to track down that 
particular piece of stupidity.  Tried everything except the obvious!!!

Sorry for the noise.

cheers (said he, not very cheerfully),
