Create visual, interactive, data-based web applications without having to be a web developer

Overview

In Shiny R LiveLessons, Jared Lander shows you how to use Shiny to your advantage. Shiny is an open source web framework for R and Rstudio that enables you to turn analyses into visual, interactive applications. Shiny applications are easy to write and are built with R. No web development skills are necessary.

Lesson Descriptions

Lesson 1: Getting Started with Markdown

Markdown is an excellent tool for writing documents. It enables you to focus on content and not be distracted by design. Highly flexible, it can render elegant HTML files, professional PDFs, editable Word documents, web slideshows, and more. You learn the basic structure of Markdown documents and how easy it is to write page after page.

Lesson 2: Integrating Code into Markdown

Weaving together R code with prose has been a hallmark of scientific writing in R for many years thanks to S-Weave and knitr. Now with RMarkdown it is easier than ever before. We go over the necessary steps to integrate R code into Markdown documents for easy blending of results and explanations.

Lesson 3: Shiny in RMarkdown

Getting started with Shiny can seem daunting at first, having to deal with server-side and UI-side code. This endeavour does not have to be intimidating, however, because Shiny can be integrated into RMarkdown with ease. We learn the basic concepts of Shiny, such as user inputs and rendering outputs, all within a single-file RMarkdown document.

Lesson 4: Reactive Expressions

The underpinning of Shiny is reactivity. This is how objects are updated based on changes in other objects. We cover the basics of what is needed to know in order to avoid trouble while building Shiny apps.

Lesson 5: flexdashboard

The flexdashboard package enables the creation of stunning web layouts, powered by R, written entirely in RMarkdown. We create a document that looks and feels like a full website and add Shiny components for interactivity.

Lesson 6: shinydashboard

Traditional Shiny apps depend upon UI and server files which separate form from function. With shinydashboard we can quickly build professional web apps that are highly customizable. We go through layout considerations and how to incorporate input and output objects. We then integrate HTML widgets, use shinyjs to incorporate JavaScript functionality and enable the creation of user-generated reports.
