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]')
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)
