Thanks to Deepayan...again, for suggesting "parse". Here is how I added the degree symbol to a vector of text for my xyplot legend:
auto.key =list(points = FALSE,text=parse(text = paste(levels(as.factor(divertSST2$temp)), "*degree", sep = ""))), For me the tricky part was learning about adding the '*'.

I think the problem is that you want a vector of expressions, and that's a bit harder to get. I'm not sure what the best solution is, but if everything else fails, you could try using parse(text=) -Deepayan ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
