Here is a way.

ggplot(jjdata, aes(x=x, y=y))+
   geom_text(x=3, y=7.5, label=expression(paste(R^2 == '0.23')))

Hope this helps,

I want R-squared to be shown in standard notation, i.e. capital R followed by a super-script 2 and then =0.23 as standard (i.e. non-superscripted text). I have tried the follow, but it does not work:
