[R] ggplot sub- and superscript for axis name

2010-08-31 Thread Benoit Boulinguiez 

Hi all,

For publication purpose, I require to label ggplot figures axes with  
sub- or superscript text.
I tried several ways, but never worked so far, to mix character  
string, sub- or superscripting on it and even worse, mathematical  
symbols.


Let say I want to write the LateX equivalent of \gamma_{fi} in a  
ggplot element name, how can I do that?



#dumb example

foo-data.frame(a=seq(1:100),b=rnorm(100,1,1))
p-ggplot(data=foo,aes(x=a,y=b))
p-p + geom_point()
p-p + scale_x_continuous(name='gamma[fi]')
print(p)



Regards
Ben

Try:
p-p + scale_x_continuous(name=expression(gamma[fi]))

(I was, however, wondering if you were misspelling phi? But the I  
don't know any LaTeX.)



print(p)

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
