R version 2.9.0 was released to the central CRAN mirror on Friday, and source and binary distributions are now available at most mirrors worldwide. You can see a complete list of new features on CRAN. The biggest change is that the Matrix package is now part of the official R distribution, greatly enhancing R’s capability for efficiently processing sparse and dense 2-dimensional numerical matrices.
Here at REvolution Computing we don’t support bleeding-edge CRAN R releases until they’ve proven stable in the field. We currently offer REvolution R 1.3 for free download, and discussion and community help is available on the REvolution R forum. (For full technical support and other additional features, consider subscribing to REvolution R Enterprise.)
