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)
