R help - Nov 2009 - How to change the label font size?

The labels on the axis overlap. Is there a way to change their font
size smaller?


m=100
n=100
X=replicate(n,rnorm(m))
image(X,axes=F)
axis(side=1,at=seq(from=par()$usr[1],to=par()$usr[2],length=(m+1))[1:m],labels=replicate(m,
'A'),las=2)

Hi again Peng,
The "cex.axis" argument will change the axis font size (e.g. cex=0.5),
but you may find that the staxlab function in the plotrix package will 
also solve the problem.
