Hands-On Dashboard Development with Shiny

By: Chris Beeley

Overview of this book

Although vanilla Shiny applications look attractive with some layout flexibility, you may still want to have more control over how the interface is laid out to produce a dashboard. Hands-On Dashboard Development with Shiny helps you incorporate this in your applications. The book starts by guiding you in producing an application based on the diamonds dataset included in the ggplot2 package. You’ll create a single application, but the interface will be reskinned and rebuilt throughout using different methods to illustrate their uses and functions using HTML, CSS, and JavaScript. You will also learn to develop an application that creates documents and reports using R Markdown. Furthermore, the book demonstrates the use of HTML templates and the Bootstrap framework. Moving along, you will learn how to produce dashboards using the Shiny command and dashboard package. Finally, you will learn how to lay out applications using a wide range of built-in functions. By the end of the book, you will have an understanding of the principles that underpin layout in Shiny applications, including sections of HTML added to a vanilla Shiny application, HTML interfaces written from scratch, dashboards, navigation bars, and interfaces.

We will take out the sidebar menu buttons that we used in the previous section to switch between different pages in the dashboard, and lay everything out on one page. Also, we will look at the use of tabbed boxes, for when you want one box to contain several pieces of content.

Let's look at the application here. We've upgraded the table to a data table using the DT package, because it can be made to scale better on the page. To pick the movie, it's displayed right next to the table, and the graph and year selector are below it, as shown in the following screenshot:

A dummy control is placed next to the real control to give a better example of how to lay out multiple elements, and how they look. The movies selector...
