Thanks! I could not figure this out yet, butI was thinking: can I not use the ascii key (I guess it would be 0228) then? But how would I do this? Btw, I really would like to use omega in an example but I figured that the usual way of writing Greek characters would work there. I tried the following: require(ggplot2) data<-as.data.frame(c("a","b","c","a","b","c")) colnames(data)<-"Y" data$X<-c(1:6) data$Z<-c(1,2,3,1,2,3) ggplot(data, aes(x=X)) + geom_line(aes(y = Z), size=0.43) + xlab(expression(atop(top,bold(Age~"\0228"(omega))))) but I do not get what I want. Looking around, it is not clear to me that I can get this to work. The ASCII codes that I saw were all specific to a letter with umlaut. I want \omega with the double dots (umlaut). Thanks again!
