R help - Sep 2008 - x axis label overlap

Hello,

On the figure produced by this code:

##############
# données Bacher 2001
y
.bacher
c
(69,18,13,12,5,4,3,3,13,9,7,6,4,2,69,19,12,40,5,2,2,2,51,18,8,31,9,3,2,2
)
x.bacher=c(seq(1:6),8,9,seq(9,13), 
15,15,16,17,17,18,19,20,22,22,23,25,25,26,27,28,30)

# graphe
#quartz(width=2.12,height=2.12)
quartz(width=10,height=10)
par(mar=c(5.1+2,4.1+2,4.1,2.1))
plot(x.bacher,y.bacher,type="b",xlab="time",ylab="number
of
prey",cex.lab=2,pch=19,axes=FALSE)
axis(1, at = c(1,9,15,17,22,25), side=1, labels = c("9 July","17
July","23 July","25 July","30 July","1
August"),adj=1,cex.axis=1.8)
axis(2,cex.axis=1.8)
box()
#############

I want the x axis labels not to overlap, but without changing the size  
cex.axis=1.8 and without rotating them. Any idea?

Hi Thomas,
Have a look at staxlab in the plotrix package.
