We don't have a way of formatting numbers according to LC_NUMERIC, as
far as I know. This leaves it to you to set up axes etc. to your
liking, e.g.

 x <- rnorm(100,,.2)
 p <- pretty(x)
 axis(1, at=p, labels=sub("\\.", ",", p))

(and possibly throw in xlim=range(p) on the hist() call. Or use
axTicks(), which is probably a better idea.)

This should improve in 2.1.0 (or at least be broken in new and
interesting ways) due to support for UTF-8 encodings.
