What’s New in 6.2: Open Source R 2.15.3

by Thomas Dinsmore

Last week, Revolution Analytics released the Limited Availability edition of Revolution R Enterprise Release 6.2.  Interest in this new release is high, and we're very pleased with user response. Over the next several weeks, I will share more detailed information about the capabilities included in this new release.

Revolution R Enterprise Release 6.2 supports open source R 2.15.3, the latest stable version.  Release 6.1, our current GA release, supports open source R 2.14.2.  Revolution R Enterprise users who upgrade to Release 6.2 benefit from 89 new features, 11 performance enhancements and 139 bug fixes in the open source R software releases.

Here are brief summaries of the new capabilities in each open source R release:

• R 2.15.0
• R 2.15.1
• R 2.15.2
• R 2.15.3

But that's not all.  R package developers work on a different cadence from the R Project as a whole.  There are at least 137 CRAN packages with new releases that depend on R 2.15.x, including:

• devtools
• arules
• Matrix
• lasso2
• fGarch
• Rcpp
• tree
• lattice
• Rsurvey

There are also some recently released independent R packages, such as RStan, that depend on R 2.15.  If you use any of these packages, Revolution R Enterprise Release 6.2 enables you to upgrade to a more recent version.

In the next post, I'll write about our exciting new capability for Stepwise Regression with Big Data.
