[R] lattice: How to vertically adjust an axis label?

[Marius Hofert]

Dear expeRts,

How can I vertically adjust an axis tick label so that it is nicely aligned with
the other labels?

library(lattice)
xyplot(0~0, xlim=c(0,3), scales=list(x=list(at=c(1,1.1), labels=c(expression(hat(theta)[italic(n)]),expression(theta)))))
## aim: move the leftmost expression up so that theta is nicely aligned with the second theta.

Cheers,

Marius
