[R] contour doesn't obey cex.axis?

[Greg Howard]

I can't seem to control the size of the numeric labels for my contour
plots.  I am using "cex.axis", which works with plot():

this makes the tick mark labels very large
plot( 1:3, 1:3, cex.axis=2.0, )

but this doesn't change them:
contour( 1:3, 1:3, array( data=0:9, dim=c(3,3) ), cex.axis=2.0, )

Is there a replacement for cex.axis in contour()?

thanks,
