NOTE: Please use https://community.rstudio.com for discussing Shiny questions. We are moving away from this Google Group.

Shiny is a package from RStudio that makes it dramatically easier to build interactive web applications with R. You don't need to know anything about web applications to get started--with just some R knowledge and our tutorial, you'll be writing Shiny apps in no time! Go to the Shiny home page to learn more and see examples.

Post your comments and questions (and answers!) about Shiny here, or show us a gist of your latest Shiny app!
