R help - Apr 2014 - cex values being ignored in the curve function

Dear R-Community,

The cex values in curve seem to be being ignored. I have searched 
previous help questions and also the web generally, and cannot find this 
being a major problem so I am suspicious of something odd happening but 
I am at a loss to work out why.

I am trying to plot this:

b1      <- -0.858
pow    <- 0.8
ratio   <- 1
sig      <- 0.05

curve((qnorm(1-sig/2)+qnorm(pow))^2/b1^2/x/(ratio/(1+ratio))/(1/(1+ratio)),from=0.005,to=0.08,main="This
needs to be bigger",xlab="And this bigger too",ylab="And
this too",
cex=1,cex.lab=3.5, cex.axis=3.5, cex.main=3.5, cex.sub=3.5)

But no matter what value of cex I make it, or whether I break up the 
arguments into :

title(main="something",cex.main=3)
axis(cex.axis=2)

or parse this before plotting : par(cex.lab=1.5, cex.axis=1.5, 
cex.main=3.5, cex.sub=1.5)

I cannot get the main, axis titles or axis numbers to change in size, 
whatever I do.

I am using a macbook pro, with mavericks, R-studio and R 3.1.0 
"spring-dance", and I am initiating the plot with:

X11( width=width , height=height , type="cairo").

Any help would be greatly appreciated.

thanks
Philip

Don't know if this helps, but works for me on a PC under Windows 7
with the default graphics device. Try a different device, maybe (e.g.
pdf) ??
