# Shiny
|
|
|
|
Shiny is a new package from RStudio that makes it incredibly easy to build interactive web applications with R.
|
|
|
|
For an introduction and examples, visit the [Shiny homepage](http://www.rstudio.com/shiny/).
|
|
|
|
## Features
|
|
|
|
* Build useful web applications with only a few lines of code—no JavaScript required.
|
|
* Shiny applications are automatically "live" in the same way that spreadsheets are live. Outputs change instantly as users modify inputs, without requiring a reload of the browser.
|
|
* Shiny user interfaces can be built entirely using R, or can be written directly in HTML, CSS, and JavaScript for more flexibility.
|
|
* Works in any R environment (Console R, Rgui for Windows or Mac, ESS, StatET, RStudio, etc.)
|
|
* Attractive default UI theme based on [Twitter Bootstrap](http://twitter.github.com/bootstrap).
|
|
* A highly customizable slider widget with built-in support for animation.
|
|
* Pre-built output widgets for displaying plots, tables, and printed output of R objects.
|
|
* Fast bidirectional communication between the web browser and R using the [httpuv](https://github.com/rstudio/httpuv) package.
|
|
* Uses a [reactive](http://en.wikipedia.org/wiki/Reactive_programming) programming model that eliminates messy event handling code, so you can focus on the code that really matters.
|
|
* Develop and redistribute your own Shiny widgets that other developers can easily drop into their own applications (coming soon!).

|
## Installation
|
|
|
|
To install the stable version from CRAN, simply run the following from an R console:
|
|
|
|
```r
|
|
install.packages("shiny")
|
|
```
|
|
|
|
To install the latest development builds directly from GitHub, run this instead:
|
|
|
|
```r
|
|
if (!require("devtools"))
|
|
install.packages("devtools")
|
|
devtools::install_github("shiny", "rstudio")
|
|
```
|
|
|
|
## Getting Started
|
|
|
|
To learn more we highly recommend you check out the [Shiny Tutorial](http://rstudio.github.com/shiny/tutorial). The tutorial explains the framework in-depth, walks you through building a simple application, and includes extensive annotated examples.
