February 12, 2009
By

A few days ago, I started a new project called RInside by uploading a few files to a new SVN repo at R-Forge. RInside makes it easy to embed R into your own C++ application by hiding the nitty gritty of initializing an R interpreter behind a simple abstraction. More information is at a (currently pretty simple) RInside...

February 3, 2009
By

We have started to look into kdb+ as a possible high-performance column-store backend. Kx offers free trials -- and so I have played with this for a day or two, both the general system, data loads and dumps and in particular with the interface to R, Based on the few files (one C source with interface code, one R file to access the...

January 14, 2009
By

Version 0.1.2 of r (pronounced littler) was just rolled up. This version adds two new command-line switches: -t selects per-session temporary directories in the same way as R does (with thanks to Paul Gilbert for the suggestion), and -q skips autoloading of default libraries at startup for another small yet noticeable gain in startup speed (with thanks to Simon Urbanek). As usual, our code in...

One aspect merits further highlighting. The reporter asked whether R would pose a threat to SAS: "I think it addresses a niche market for high-end data analysts that want free, readily...
