[R] plot + axis: Individually moving tick labels with hadj?

[Sarah Goslee]

Hi Marius,

I actually prefer the first (default) arrangement, with the labels centered, but
if you want to align the equals under the tick mark one option is to use
axis() twice:

plot(1:5, 5:1, xaxt="n")
axis(1, at=1:5, labels=c(1,2,"",4,5))
axis(1, at=3.15, tick=FALSE, labels=expression(3==beta[foooooo]))
