Example from the mathjax demo:

When \(a \ne 0\), there are two solutions to \(ax^2 + bx + c = 0\) and they are

\[x = {-b \pm \sqrt{b^2-4ac} \over 2a}.\]

If I have a random $ and another $ in my text.

Preview Image

plt <- ggplot2::ggplot(ggplot2::mpg, ggplot2::aes(displ, cty)) +
  ggplot2::geom_point()
plt

print("hello world")

[1] "hello world"

w and s move the left paddle, o and l move the right paddle.

DT::datatable(head(iris))

Plotly

print("test")

[1] "test"

plt <- ggplot2::ggplot(ggplot2::mpg, ggplot2::aes(displ, cty)) +
  ggplot2::geom_point()
plotly::ggplotly(plt)

However, while this options brings back plotly, it also disables math rendering for this document on the site.

Example from the [mathjax demo](https://www.mathjax.org/#demo):

When $a \ne 0$, there are two solutions to `\(ax^2 + bx + c = 0\)` and they are

$$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$

If I have a random $ and another $ in my text.
