HI all,
I'm trying (unsuccessfully) to add the degree symbol to each line of
text in my legend (within xyplot).
Here is the line of code, which fails to interpret the expression
function:

auto.key =list(points =
FALSE,text=paste(levels(as.factor(divertSST2$temp)),expression(degree)).
..),

I just get:
7 degree
8 degree
9 degree

If I place 'expression' outside or just after the paste function it also
doesn't work.
Any suggestions are well received!
Thanks
Michael Folkes
