[R] GGPLOT: Superscript text in body of plot

[Rui Barradas]

Hello,

And with annotate, the warning goes away.


ggplot(jjdata, aes(x=x, y=y))+
   geom_point(size=2,shape=1)+
   annotate(
     "text",
     x=3, y=7.5,
     label="R^{2} == 0.23",
     parse = TRUE
   )


Hope this helps,

Rui Barradas
