I am trying to create a plot that is annotated with text that contains both alpha-numeric and greek characters. If I want to add just greek characters I can use:
qplot(x, y) + geom_text(aes(2, 2, label="rho"), parse=TRUE)
How can I annotate a plot with "ρ and some other text"? I would like to do something like this:
qplot(x, y) + geom_text(aes(2, 2, label="rho and some other text"), parse=TRUE)
When I try the above code, I get this error:
Error in parse(text = lab) : <text>:1:5: unexpected symbol 1: rho and ^
I would also appreciate any solution that would allow me to use LaTeX in
geom_text() for more complex use cases in the future.
