Stats in the Wild

I’ve been interested in building a web app using R for a while, but never put any time into it until I was informed of the Shiny package.  It looked too easy, so I absolutely had to try it out.

First you need to install the package from the command line .

options(repos=c(RStudio="http://rstudio.org/_packages", getOption("repos")))
install.packages("shiny")

The version in the tutorial uses a two R files, won the front end(ui.R) and the other being the server side (server.R).  However, I wanted a refresher in HTML, so I built it with one HTML and one R file.  The structure is defined here.

For the data, I’m using MLS (home sales) data for Philadelphia, which I’ve been sitting on for quite a while.  The thought behind the app is to be able to examine monthly average listing prices to monthly average prices, and in the end it turned out rather well.
