Hello,
I would like to show in my facet labels the equivalent in LaTex of
$\sigma_{0}= \sqrt{2}$. I think I'm close below, but not yet as it shows
$(\sigma_{0}, \sqrt{2})$
m <- mpg
levels(m$drv) <- c("sigma[0]=sqrt(2)", "sigma[0]=2 * sqrt(2)", "sigma[0]= 3
* sqrt(2)")
ggplot(m, aes(x = displ, y = cty)) + geom_point() +
facet_grid(. ~ drv, labeller = label_parsed)
Thanks,
Lars.
