[R] Misplacement of Greek letter

[Peter Ehlers]

Not that I want to encourage the creation of the infamous
skyscraper plot (which has an extremely low
information/ink ratio), but if you're having trouble with
axis labelling, it's probably best to look at mtext().
You can use several mtext calls to place parts of your label
on different margin lines.
