Introducing Shiny

Shiny is a new package from RStudio that makes it incredibly easy to build interactive web applications with R. Building applications with Shiny has many compelling benefits, including:

• Automatic reactive data-binding between inputs and outputs that makes it possible to build useful applications with only a few lines of code.
• Shiny user-interfaces are "live" in the same way that spreadsheets are live. Outputs change instantly as users modify inputs without explicit programming or requiring a reload of the browser.
• Applications can be built entirely using R, or can optionally make use of custom HTML, CSS, and JavaScript.
• A highly customizable slider control that has built-in support for animation.
• Pre-built output widgets for displaying plots, tables, and printed output of R objects.
• Fast bi-directional communication between the web browser and R using the websockets package.

Getting Started

If you've already got the Shiny package installed you are ready to go. If you don't have Shiny yet you'll need to:

• Request access to the beta by sending email to info@rstudio.org.
• Once you have been granted access to the beta download and install the Shiny package from GitHub at https://github.com/rstudio/shiny.
