Re: ggplot2-superscript in axis.title-conflict with ylab(expression(paste(.....))) and opts(axis.title.y

[Brandon Hurr]

Other than needing to use the new system (assuming you're in 0.9.2.1) it should work fine (it does on my machine).

qplot(1:10, 1:10)+
labs(y=expression(paste(log~Biovolume~µm^3~L^-1)))+
theme(axis.title.y = element_text(size=32,face="bold", colour="black",angle=120, vjust=1))
