Getting started with Wikipedia Preview • wikipediapreview

Setup

Initialize Wikipedia Preview by including the following inline code anywhere in your R Markdown document:

`r wikipediapreview::wp_init()`

Note: If you prefer to have a designated chunk, initialize with the following code instead:

```{r wp-init, results='asis', echo=FALSE}
library(wikipediapreview)
wp_init()
```

Usage

The library automatically detects Wikipedia links.

You can also make those links stand out and appear different from non-Wikipedia links using the built-in style:

Source:

[Stan](https://mc-stan.org/) samples via
[HMC](https://en.wikipedia.org/wiki/Hamiltonian_Monte_Carlo){.wiki}

Output:

Stan samples via HMC

Wikipedia Preview works with all the language editions of Wikipedia.

Alternative style

The default styling is the one provided and used by Wikimedia’s Inuka team which developed Wikipedia Preview. The author of this package prefers a different styling and has made it available via the use_alt_style flag when initializing:

`r wikipediapreview::wp_init(use_alt_style = TRUE)`

Wikipedia links will be marked with a W that looks similar to the Wikipedia logo.

Linking

By default wp_init() will embed the JavaScript code in the page. The Wikipedia Preview JavaScript library is available via a CDN – specifically unpkg. To use that instead of embedding for bandwidth and performance benefits:

`r wikipediapreview::wp_init(use_unpkg = TRUE)`
