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) Thomas __ Thomas Szegvary Institute of Environmental Geosciences Department of Geosciences University of Basel Bernoullistrasse 30 CH - 4056 Basel Tel. 41-61-267 04 82 Fax. 41-61-267 04 79 Email: [EMAIL PROTECTED] www.radon.unibas.ch www.unibas.ch/environment -----Ursprüngliche Nachricht----- Von: hadley wickham [mailto:[EMAIL PROTECTED] Gesendet: Freitag, 20.
