I would like to add annotate text with the label: 

lambda = £5,000/Q.

But where lambda is a Greek letter.

Parse inside text doesn't accept £ or ,

All the guidance online seems to point towards combining text. So "5000/Q" is not a problem but I really would like the £ and the ,.

Any ideas?

Edit because perhaps I wasn't clear enough that it is the character symbols (£ and ,) that are giving me troubles.

Let's take this as an example:

ggplot(data=data.frame(y=c(1,2,3),x=c(1,2,3)), aes(y=y, x=x)) + geom_point() + annotate("text", label="lambda", x=2, y=2.5, parse=T)

No problem, right? Now try and add a '£' symbol.

ggplot(data=data.frame(y=c(1,2,3),x=c(1,2,3)), aes(y=y, x=x)) + geom_point() + annotate("text", label="lambda~£", x=2, y=2.5, parse=T)

And here's the error:

Error: <text>:1:8: unexpected input
1: lambda~£
           ^

This has not been addressed in any other stackoverflow post to my knowledge.

Any ideas?

  • I've seen both of those posts but neither of them use special character symbols £ or ,. I can also easily put in an equals sign and some letters. But I cannot put a £ or , with those methods. Any ideas? – jnam27 Jul 11 '14 at 09:47
  • how about `parse = FALSE` and `label="λ = £5.000/Q"` – baptiste Jul 11 '14 at 11:43
