What is R?

R is an open source programming language for statistical computing, data analysis, and graphical visualization. R has an estimated one million users worldwide, and its user base is growing. While most commonly used within academia, in fields such as computational biology and applied statistics, it is gaining currency in commercial areas such as quantitative finance and business intelligence.

Among R's strengths as a language are its powerful built-in tools for inferential statistics, its compact modeling syntax, its data visualization capabilities, and its ease of connectivity with persistent data stores (from databases to flatfiles).

In addition, R's open source nature and its extensibility via add-on "packages" has allowed it to keep up with the leading edge in academic research. The Comprehensive R Archive Network (CRAN) is an online repository with nearly 1500 packages, which extend R to applications from gene microarray analysis to Black-Scholes estimation of equity options.

For all its strengths, though, R has an admittedly steep learning curve; the first steps towards learning and using R can be challenging. Beyond consulting the growing number of textbooks that are being published, interacting with other R programmers can be an invaluable way of improving one's skills.

Towards this end, the Bay Area R Users Group is dedicated to bringing together area practitioners of R to exchange knowledge, inspire new users, and spur the adoption of R for innovative research and commercial applications.
