[R] How to use parentheses and degree symbol together?

[Patrick Connolly]

I'm interested in using a regular bracket with the degree symbol as an
axis label but it's somewhat simpler to show what I mean in a text
statement.

> plot(0, 0, pch = "")

If I'm easy to please, this would suffice:
> text(0, .5, expression(Temperature * degree ~ C))

But I'm not that easily pleased.  I prefer it to look like this:
> text(0, .4, substitute(paste(Temperature, B * degree, "C)"), list(B = " (")))

It looks fine, but I'm sure there's a more elegant way to do it.

Is there?
