The cex parameter to mtext will change the size of its text, values  
greater than 1 are an increase.

cex.axis and cex.lab change the size of the axis scale and axis label,  
these can be either in the par statement or in the plot. The axis  
labels may then need to be shifted slightly. I think there is a  
parameter for this, and it will be in the help on par.

Sometimes plotting into a small page using the width and height  
parameters to postscript will make the plots look better.
