This function makes it slightly easier to render TeX in a plotly graph -- it ensures that MathJax is included with the final result and also ensures the provided string is surrounded with $ (this is what plotly.js uses to declare a string as TeX).
$
TeX(x)
a character vector
config
plot_ly(x = c(1, 2, 3, 4), y = c(1, 4, 9, 16)) %>% layout(title = TeX("\\text{Some mathjax: }\\alpha+\\beta x")) %>% config(mathjax = "cdn")
