[R] ggplot sub- and superscript for axis name

[Ista Zahn]

Hi Ben,
Since you already know LaTeX, I would go with what you know. Try

p<-p + scale_x_continuous(name='$\\gamma_{fi}$')

library(tikzDevice) ## may too to install first

tikz(file="foo.tex", standAlone=TRUE)
print(p)
dev.off()

system("pdflatex foo.tex")

Best,
Ista
