Math symbols in ggplot facets
Hi:
You were close...
library(ggplot2)
m <- mpg
# Set the factor labels with plotmath code (note the ==)
m$drv <- factor(m$drv, labels = 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)

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.
