The given solution is the right one for the degree symbol, but does not
answer the overall question of how to superscript, in particular how to
superscript with nothing actually preceding the superscript.
In general "^" is used to obtain superscripts in plotmath (RTFM!) and if
nothing comes before the superscript, replace the nothing by {}.
The following seems to work:
plot(1:10,xlab="",ylab=expression(Temperature~{}^o*C))
The degree symbol however may be rendered better by "degree" than by "{}^o".
cheers,

Hi,
Try:
x <- 1985:1990
set.seed(45)
y <- sample(70:90,length(x),replace=TRUE)
plot(x,y,xlab="Year",ylab=expression(Temperature~degree*C),main="April Average Temperature
1985-1990",type="p")
A.K.
I want to provide a label for my x,y plot as such: ylab="Temperature
(^oC)", where the o is meant to be superscripted. This isn't working.
I've googled it and looked at the user manual but I can't figure it out.
Can anyone explain the mechanism for superscripting something please?
I've tried: plot(x,y, xlab(expression(Year)),
ylab(expression(Temperature(~{o}~C))", main(expression(April Average
Temperature 1961-2010)), type="p"),
and I've tried some other things that I can't remember all of now.
Very confused. It should be a simple thing to superscript something in a
heading!
