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))))) -Deepayan On Thu, Feb 13, 2020 at 11:36 AM Bert Gunter <bgunter.4...@gmail.com> wrote: > > OK.
