# ggplot2 latex trick

This is a useful package to use latex notation in {ggplot2}. I saw this on twitter and wish I had written down the originator for proper citation but I forgot at the time.


library(tidyverse)
library(latex2exp)

example_data <-tibble(ability = seq(-3,3, .1)) %>%
mutate(result = plogis(ability*2))

example_data %>%
ggplot(aes(ability, result))+
geom_line()+
labs(
x = TeX("$ability(\\theta)$")
)+
theme_bw()


plogis(3)

[1] 0.9525741

exp(3)/(1+exp(3))

[1] 0.9525741
