Unbelievable and Amazing R Shiny–Web Parameter Test in 1.5 Hours

Life keeps getting better and better.  Yesterday, I discovered the absolutely unbelievable and amazing work RStudio has done with Shiny employing one of my favorite R packages websockets.  As proof of the ease and quality, within a couple of minutes, I was able to get it up and running.  This morning basically starting from scratch in less than 1.5 hours I was able to achieve a web-based interactive parameter test for a moving average system as my first example.

Below is a screencast of this very basic parameter testing web app.  I can only hope that this simple application can illustrate just how powerful Shiny is.  Just imagine pairing this with d3 or knitr.

R code for server.R and ui.R from GIST:
