title: "Test: Output Rendering"

```{r include = FALSE}
knitr::opts_chunk$set(collapse = TRUE, comment = "#>")
```

This vignette tests pkgdown output rendering for several use cases.

# Highlighting

This document uses a variety of linking styles for testing purposes

## Inline code

Local:

* `vignette("pkgdown")`
* `build_site()`
* `?template_navbar`

Remote:

* `MASS::enlist`
* `MASS::enlist()`
* `?MASS::enlist`
* `%in%`
* `` ?`%in%` ``

## Spurious links

These shouldn't be linked.

* `Authors@R`
* `content-home.html`
* `toc: depth`
* `x = y`

## Code blocks

```{r, eval = FALSE}
# Shouldn't get linked
enlist(5)
# Should get linked
MASS::enlist(5)
```

```{r}
library(MASS)
enlist(5)
```

```{r}
# Should get linked because MASS was loaded previously
enlist(5)
```

# Mathjax

$$f(x) = \dfrac{1}{\sqrt{2\pi\sigma^2}} e^{-\frac{(x-\mu^2)}{2\sigma^2}}$$

Inline equations: $y=x^2$

# Widgets

Test spacing above widget.

```{r, echo=FALSE}
# set seed for reproducible widget id
if (requireNamespace("htmltools", quietly = TRUE)) {
  htmlwidgets::setWidgetIdSeed(42)
}

library(leaflet)

leaflet() %>%
  addTiles() %>%
  addMarkers(
    lng=174.768,
    lat=-36.852,
    popup="The birthplace of R"
  )
```

Test spacing below widget.
