What is Shiny

Shiny is an R extension package that that makes it easy to build interactive web apps. This is the reason it is ideal for quickly making prototypes, but it is also a decent choice for building production-ready applications.

info

Shiny combines the power of R with the interactivity of the modern web. See this tutorial and book for accessible introductions.

We are going to build this simple Shiny app next.

The following sections will show how Shiny apps are structured:

  1. the user interface (UI),
  2. the server function,
  3. and the app that contains the UI and the server.
