I am on a class-taking spree.  I finished up Practical Machine Learning Coursera class, and just started in on the Developing Data Products class. What is a data product?  Here’s a short description of the course: 

A data product is the production output from a statistical analysis. Data products automate complex analysis tasks or use technology to expand the utility of a data informed model, algorithm or inference. This course covers the basics of creating data products using Shiny, R packages, and interactive graphics. The course will focus on the statistical fundamentals of creating a data product that can be used to tell a story about data to a mass audience.

The final project for the class is to make a Shiny app.  Shiny lets you make a webpage that runs R in the background.  This blows my mind!  I just made my very own shiny app to calculate sample sizes for one-sample t-tests.  This fulfills the final project requirements for the class, but now that I know how to make a shiny app, I don’t want to stop!  Check out the Shiny website and try it for yourself.
