R and Big Data at Big Data Summit at UI Research Park
I spent yesterday at the very enjoyable Big Data Summit held at the University of Illinois Research Park at the edge of the University of Illinois at Urbana-Champaign. campus. My (short) presentation was part of a panel session on R and Big Data which Doug Simpson of the UIUC Statistics department had put together very well. We heard from a...

RcppArmadillo 0.3.930.1
A new Armadillo release 3.930 came out a few days ago, with a very nice set of changes (see below). I rolled this into RcppArmadillo 0.3.930.0. However, one of these changes revealed that R shipped only the standard SVD for complex-valued matrices, and not the more performant divide-and-conquer approach. So in R builds using the default built-in...

A maintenance release (now at version 0.2.5) of my gcbd package (described only in these two posts) is now CRAN. More details about the package are available in the paper which is also included in the gcbd R package.

The package is described in a detailed vignette as well as in a essay by Mads Haahr. Changes were minimal and driven mostly by some CRAN Policy changes which now prefer vignet...

New RcppEigen release 0.3.2.0.1 — and a new maintainer
In a recent email to the Rcpp and lme4 mailing lists, Doug Bates announced that was turning away from R, Rcpp, lme4 and hence also RcppEigen for which he had been both the primary author and maintainer. This is huge loss for the R community. I have known Doug since the 1990s. He has been a fairly central figure around R during all those years in...

RcppZiggurat 0.1.0 (and 0.1.1): Faster N(0,1) RNGs
Over the last few weeks I have been working on getting the Ziggurat normal random number generator updated and available in R. The Ziggurat generator provides a pretty unique combination of speed and good statistical properties for (standard) normal random numbers (as opposed to uniform draws as is commonn for most RNGs). Generation of N(0,1) dr...

This release comes from a rewritten build script for the package. We no longer drive the initi...
