How do I include a superscript to texts on a plot on R?

Question

I need it to look like this:

R^2 = some values

And I\'ve tried the code below but it wouldn\'t work, it came out as \"R (expression (^2)) = some values\" i

Answer 1

The paste function returns a string, not an expression. I prefer to use bquote for cases like this:

text(25, 200, bquote( R^2 == .(rs), list(rs=round(rsquarelm2,2))))
