[R] rotating axis / mtext labels

[Iain Gallagher]

Hello list.

Is it possible to use par(srt=45) to rotate text by 45 degrees along the 
x-axis of a plot. Using:

<code>

x_names<-c("C57 Nv", "C57 Vacc", "129 Nv", "129 Vacc", "IFNgR Nv", "IFNgR Vacc")
par(srt=45)
mtext(font=2, x_names, side=1, line=1, at=l, cex=1.2)
par(srt=0)

</code>

doesn't seem to work in R 2.2.0 on SUSE linux.

Suggestions would be appreciated thanks.
