Companies using R in 2014 (Revolutions)

I'm honoured to have been invited to give a keynote presentation at the 7th China R Users Group conference in Beijing tomorrow — I'm told around 1000 R users are expected to be there. (This easily makes it the largest R users meeting in the world.) For my presentation, I decided to curate a list of some companies that are currently using open-source R and describe the applications they are using it for.

My slides are embedded below, but here is a summary of the companies and their applications (including a few that I didn't have time to present in the keynote itself — these are included in the bonus slides of the presentation).

Facebook uses R for Exploratory Data Analysis, Experimental Analysis, Big-Data Visualization, Human Resources, and user behaviour analysis related to status updates and profile pictures.
Google uses R for Advertising Effectiveness, Economic Forecasting, and Big-data statistical modeling.
Twitter uses R for Data Visualization and Semantic Clustering.
The City of Chicago uses R as a food poisoning monitor.
The New York Times uses R for interactive features (such as the Dialect Quiz and the Election Forecast); for data journalism (including these stories on NFL draft picks and wealth distribution in the USA); and for data visualization (such as in articles on the Facebook IPO and baseball pitching legends).
In video gaming, Microsoft uses R for Xbox matchmaking, and Scientific Revenue helps video game developers identify trouble-spots in game levels (and much more).
Zillow uses R to create and update the Zestimate housing price estimate, and Trulia uses R for neighbourhood crime mapping.
John Deere uses R for statistical analysis, to forecast crop yields and create long-term demand forecasts for its farming equipment.
The Human Rights Data Analysis Group uses R to create more accurate counts of casualties in war zones, and the Sunlight Foundation uses R to keep track of political speech.
In finance, ANZ Bank uses R for credit risk analysis; American Century Investments uses R to analyze financial networks; and Credit Suisse uses R on the trading desk.
The FDA uses R in the regulatory drug approvals process.
Monsanto uses R for statistical analysis in plant breeding, fertility mapping and yield forecasting.
In insurance, Lloyds of London uses R for risk analysis and catastrophe modeling; Nationwide uses R for marketing analytics; and Deloitte uses R for actuarial analysis.
RealClimate.org uses R for climate change analysis, and NOAA uses R for flood warnings.
In marketing analytics, DataSong uses R for marketing attribution analysis; Exelate uses R for real-time ad selection; and X+1 uses R for consumer segmentation.
The list of software vendors and services companies with products related to R includes: Revolution Analytics, RStudio, Mango Solutions, Coursera, Zementis, DataCamp, SAS, Oracle, IBM, Teradata, TIBCO, Alteryx and SAP (amongst many others).

That's just a tiny fraction of the companies using R worldwide, but it goes to show: pretty much every industry now sees data and analytics as a strategic competitive advantage, and the fact that R is the language of choice of for data scientists is driving its rapid growth.
