[R] Expression in plot text

I'd like to put a degree symbol in the title of a plot. Something like:
plot(1,main=expression("Data at " * 45 * degree * " North"))
That works fine, but I like the 45 to be the value of a variable, instead of a
constant, an in:
lat <- 45
plot(1,main=expression("Data at " * lat * degree * " North"))
But this doesn't work of course, the graph title is "Data at lat° North". If
I try to paste expressions and strings together, that doesn't work either.
Now, I can figure out how to stick an ASCII 176 character into a text file and
get an actual degree symbol inside a literal string that way, though it's
rather a pain, and it shows up as "45\260 North" in an xterm. But what if I
want some other kind of expression that I can't just type in as a string?
