R help - Jun 2009 - Superscript in y-axis of plot

Dear all,

I've been trying to superscript the '2' in the following command (I
don't want the '^' displayed), but as yet haven't had much luck.
I've tried both the paste and expression commands, but neither have brought
me any joy!

mtext(side=2, line=5.5, "Monthly Precipitation (mm x 10^2/month)",
font=2, cex=1.1)


Any advice would be much appreciated,

Steve

expresison() routinely confuses me, too, although I've used it many times
before... This should work:

mtext(expression(paste("Monthly Precipitation (mm x
",10^2,"/month)"))

?plotmath is full of good examples.

For the sake of brevity, I like to use this trick,


plot(0, 0)
mtext(~"Monthly Precipitation (mm x "*10^2*"/month)")
