I'm trying to annotate a plot with R² value and significance coding, but I can't pass *
as a symbol and not as the juxtaposition operator.
I've tried ?plot.math
, here is what I tried
plot(1:10,1:10)
text(6,4,expression(R^2==8))
text(6,4,expression(R^2==8^{**}))
Error: unexpected '^' in "text(6,4,expression(R^2==8^{**"

You need to use paste
inside your expression:
text(4,6,expression(paste(R^2==8^"**")))
or
text(6,4,expression(paste(R^2==8, "**")))
