[R-sig-Geo] Adding R-square to linear regression

[Thomas Szegvary]

Thanks, I already checked plotmath. But the problem is that the symbol
itself works fine with expression(R^2), but if you want to combine plain
text with the symbol, expression() doesn't work. But I found a solution,
bquote is the magic word:


mtext(line= -1,side=3,bquote(R^2
==.(round(summary(lm4)$r.squared,3))),col="red",cex=0.7)

Have a look at ?plotmath.
