AirBnB is a top tier company that uses R packages to scale data science. In small data science teams, individual contributors often write single functions, scripts, or templates to optimize their workflows. As the team grows within the company, different people develop their own tools to solve similar problems. The package is developed in an internal Github Enterprise repository. There, users can submit issues and suggest enhancements. As new code is submitted in a branch, it is peer reviewed by an Rbnb developers group. Once the changes are approved and documented, they are merged into the master codebase as a new version of the package.

So… In class, as we all know, there was lots of moaning and groaning about the ease of use of R. Well good news (maybe?) is that R, specifically Revolution Analytics, the R-language and data crunching specialist, has been acquired by Microsoft in 2015! The main task of Microsoft is to make the data mining giant more user friendly and eventually monetize it. While the aptly named, Microsoft R (Microsoft Data Science Virtual Machine), embraces the open source of the traditional, they are after all for profit company. R is currently being used by magnates such as Facebook, Twitter, Uber, AirBnB, IBM and Google for data analytics and there is lots of interest in the tech world to see what Microsoft has in mind for this new venture.

The New York Times uses R for interactive features, data journalism, and data visualization. For example, they created a visualization to show Mariano Rivera’s baseball performance in comparison to other MLB pitchers’ performances. The graphic started as a hand-drawn sketch but then was created into a line-chart using R.

The article I read talked about R being used to help people in the financial services sector. R is adaptable and able to change with the needs of the user so it is perfect to use for financial services. It is also able to easily calculate everything needed for financial services and makes everything fast. The article I read links to a 40 minute talk about how this is helping to change financial services today.
