There is a good story in The New York Times about the R statistical programming language entitled Data Analysts Captivated by R’s Power. Analysts are using R more and more at The Genome Center. An entertaining quote in the article comes from R's competition:

“I think it addresses a niche market for high-end data analysts that want free, readily available code," said Anne H. Milley, director of technology product marketing at SAS. She adds, “We have customers who build engines for aircraft. I am happy they are not using freeware when I get on a jet.”

Is there anyone who still does not see through this FUD from proprietary software companies when talking about their free software competitors? Oh, and it's not "freeware", it's free software.
