[R] Postcript font size

[Andre Nathan]

Hello

I'm doing a number of plots and in all of them I'm specifying the same
font size. However, comparing one plot to the other, they have fonts of
different sizes, so it appears some scaling is being done.

I tried using both postcript(pointsize = ...) and par(ps = ...), but the
results were the same.

Is there a way to specify a font size that is consistent among calls to
plot()?

Thanks,
Andre
