Web Application Development with R Using Shiny - Third Edition

A minimal HTML interface

Now that we have dipped our toes into HTML, let's build a (nearly) minimal example of an interface entirely in HTML. To use your own HTML in a Shiny application, create the server.R file as you normally would. Then, instead of a ui.R file, create a folder named www and place a file named index.html inside this folder. This is where you will define your interface.
