What is R-plus?
For a very long time, there was no such thing. XLSolutions Corporation is currently beta testing a commercially supported version of R named R+ (read R plus). In addition, REvolution Computing has released RPro, an enterprise-class statistical analysis system based on R, suitable for deployment in professional, commercial and regulated environments. Random Technologies offers RStat, an enterprise-strength statistical computing environment which combines R with enterprise-level validation, documentation, software support, and consulting services, as well as related R-based products.
