Course Description

Shiny is an R package that makes it easy to build interactive web apps straight from R. Shiny combines the computational power of R with the interactivity of the modern web. This course will take you from R programmer to Shiny developer. If you want to take a fresh, interactive approach to telling your data story, let users interact with your data and your analysis, and do it all with R, dive in!

Building Web Applications in R with Shiny

This chapter lays out the basic architecture of a shiny app. You'll learn how to create the user interface and the server function for your first shiny application.

This chapter covers the basics of reactive programming. This allows you to create and reuse objects that update dynamically in response to the inputs from the user. Using reactive programming will make your apps more efficient and complex.

In this chapter you'll learn how to take advantage of different input and output options in shiny. You'll learn the syntax for taking inputs from users and rendering different kinds of outputs, including text, plots, and tables.

In this chapter you'll learn how to customize the appearance of your apps using shiny's built in functions. This will give your apps the final polish they need to be professional interactive data products!
