I'll also provide insights into how this site was made, as well as code examples and thoughts on how those could be further developed.

Embedding Shiny Apps for Interactive Data Analysis
Depending on the app, it can be built as a dashboard for reporting and analysis, extracting data or even running fully fledged machine learning algorithms based on your requirements.
This example walks you through creating an interactive Leaflet Map, publishing it to a Shiny Server and embedding it in your website.
Adding Multi-column Formats to R Markdown Documents
R Markdown supports some basic HTML elements. It also has its own notation for the <div> tag using the triple colon notation ::: for both opening and closing the element and, unlike using <div>, knitr won't auto-close these.
Learn how to use this and create a bootstrap responsive multi-column output directly from knitr.
Better Looking Tables with kable in Your R Markdown Documents
Here, I create an automated, on-the-fly table of contents without the need for hard-coded anchor links, regardless of the source of your content. It's easily adaptable to turn into a nav bar or similar menu. Similarly, this technique could be used to produce a summary with links on an API data feed page for rapid data analysis and drill-down capability.
At the end, I wrap it in a Wagtail stream block ready to drop into your templates.
Translating Static Template Text with Wagtail Localize
Static text lurks in the error pages, search results, e-mail templates and any Django pages that may be getting served on your site.
Here's an easy way to keep it all under the Wagtail Localize umbrella without the pain of making PO files and peppering your templates with blocktrans tags.
Dealing with UNIQUE Fields on a Multi-lingual Site
This poses a problem for models that have fields with UNIQUE constraints as attempting to save a copy of the default language instance will trigger an integrity error (ie duplicate key).
Fortunately, if you're using the TranslatableMixin, there's a way around this.
