2. Course Description

The Shiny package makes it easy to create interactive web applications using R.

Details

Duration 2 days
Who should attend? The course is aimed at students, academics and professionals who want to build interactive web applications.
Objectives An interactive web application is a great way to allow people to interact with data. The conventional approach to developing such an application requires knowledge of a range of web development tools. However, the Shiny package makes it possible to easily build a web application using only R. This allows you to focus on the data and user experience.
Outcomes Participants will:

  • understand the structure of a Shiny application (UI and server);
  • be able to assemble an attractive UI;
  • understand reactivity and how the UI and server communicate with each other; and
  • know how to deploy a Shiny application.
Requirements Participants are assumed to have prior exposure to R, or at least to programming of some variety. Ideally participants should have completed the Data Wrangling and Visualisation modules.

Training Philosophy

Our training emphasises practical skills. So, although you'll be learning concepts and theory, you'll see how everything is applied in the real world. We will work through examples and exercises based on real datasets.

Requirements

All you'll need is a computer with a browser and a decent internet connection. We'll be using an online development environment. This means that you can focus on learning and not on solving technical problems.

Of course, we are happy to help you get your local environment set up too! You can start by following these instructions.

Package

The training package includes access to
  • our online development environment and
  • detailed course material (slides and scripts).
