R help - Feb 2011 - superscript

Hi there, 

How can I superscript the "2" of "r2 =..." in the legend
below?

legend(210, 110, paste("r2 = ",
format(summary(regression)$adj.r.squared,digits=3), sep="")) 

I usually use "expression(paste(...", but it won't work this time
because
"format(summary(..." needs to be evaluated. 

Thanks in advance!

Would the following work?

legend(210, 110, bquote(r2
=.(format(summary(regression)$adj.r.squared,digits=3))))

See ?plotmath and ?bquote

Correction, I forgot the caret:

legend(210, 110, bquote(r^2
=.(format(summary(regression)$adj.r.squared,digits=3))))
