I know that R is free and I am actually a Unix fan and think Open Source software is a great idea. However, for me personally and for most users, both individual and organizational, the much greater cost of software is the time it takes to install it, maintain it, learn it and document it. On that, R is an epic fail.With the exception of the last sentence, I am in full agreement. Especially in the industry I work in, qualification and documentation is hugely important, and a strength of SAS is a gigantic support department who has worked through these issues. Having some maverick install and use R, as I do, simply does not work for the more formal work that we do. (I use R for consulting and other things that do not necessarily fulfill a predicate rule.)
However, another company, REvolution Computing, has recognized this need as well. With R catching on at the FDA, larger companies in our industry have taken a huge interest in R, partly because of the flexibility in statistical calculations (and, frankly, the S language beats SAS/IML hands down for the fancier methods), and mostly to save millions of dollars in license fees. Compare REvolution's few hundred dollars a year for install and operation qualification on an infinite-seat license to SAS's license model, and it's not hard to see how.
And SAS, to their credit, has made it easier to interact with R.
Epic win for everybody.
