I want to add an R^2 value to my plot. I passed the label to geom_text() as follows;
geom_text(aes(x,y,label=caption),parse=T,
data.frame(x=-2,y=80,caption=("R^2=0.43"))))
but it plots as =(R^2,0.43). Any ideas?
You want your caption to be “R^2==0.43”. Look at the help page for
plotmath. There it shows that==gives you equals.EDIT:
To answer the comment after the question, you can use atop in the expression.
"atop(R^2==0.43,p==0.763)"This works for two lines, but not more.
