shiny 
Easily build rich and productive interactive web apps in R — no HTML/CSS/JavaScript required.
Features
- An intuitive and extensible reactive programming model which makes it easy to transform existing R code into a "live app" where outputs automatically react to new user input.
- Compared to event-based programming, reactivity allows Shiny to do the minimum amount of work when input(s) change, and allows humans to more easily reason about complex MVC logic.
- A prebuilt set of highly sophisticated, customizable, and easy-to-use widgets (e.g., plots, tables, sliders, dropdowns, date pickers, and more).
- An attractive default look based on Bootstrap which can also be easily customized with the bslib package or avoided entirely with more direct R bindings to HTML/CSS/JavaScript.
- Seamless integration with R Markdown, making it easy to embed numerous applications natively within a larger dynamic document.
- Tools for improving and monitoring performance, including native support for async programming, caching, load testing, and more.
- Modules: a framework for reducing code duplication and complexity.
- An ability to bookmark application state and/or generate code to reproduce output(s).
- A rich ecosystem of extension packages for more custom widgets, input validation, unit testing, and more.
Installation
To install the stable version from CRAN:
install.packages("shiny")
Getting Started
Once installed, load the library and run an example:
library(shiny)
# Launches an app, with the app's source code included
runExample("06_tabsets")
# Lists more prepackaged examples
runExample()
For more examples and inspiration, check out the Shiny User Gallery.
For help with learning fundamental Shiny programming concepts, check out the Mastering Shiny book and the Shiny Tutorial. The former is currently more up-to-date with modern Shiny features, whereas the latter takes a deeper, more visual, dive into fundamental concepts.
