Really? What was wrong with this?


plot(1, 1, xlab=expression(32^degree) )? # the example given on ?plotmath

David,

Absolutely nothing. When there's no specific degree value in the label
because the axis represents a range of values there's no digit preceeding
the ^ symbol.

The axis label is 'Temperature (oC)' with the degree symbol preceeding a
character, not following a specific digit.

There's nothing special about following a digit. You can have it follow 
anything. Since you were going to need to quote the parentheses anywa, 
then have it superscripted above the level of the paren:


plot(1,1, ylab = expression(Temperature~"("^degree*C*")") ?
)
