R SHINY

Shiny is an R package that enables building interactive web applications that can execute R code on the backend. With Shiny, you can host standalone applications on a webpage, embed interactive charts in R Markdown documents, or build dashboards. You can also extend your Shiny applications with CSS themes, HTML widgets, and JavaScript actions.

Shiny enables you to write powerful interactive web applications entirely in R. Using R, you create a user interface and server, and Shiny compiles your code into the HTML, CSS and JavaScript needed to display your application on the web.

Since the application is executing R code on the backend, it can perform any R calculation you can run on your desktop. Perhaps you want your app to slice and dice a dataset based on user inputs. Or maybe you want your web app to run linear models or machine learning methods on user-selected data. In such cases, Shiny can help.

The Shiny web framework fundamentally enables collecting input values from a web page, making those inputs easily available to the application in R, and having the results of the R code written as output values to the web page. In its simplest form, a Shiny application requires a server function to do the calculations and a user interface. Shiny applications have two components, a user-interface definition and a server script.
