Rcpp 0.7.6
The new 0.7.6 release of Rcpp, our set of R / C++ interface classes, is now at CRAN and Debian. This comes just a few days after 0.7.5 as we had made a mistake in Makefile.win which is now fixed. A few other things sneaked in while were at it, see the snippet from the NEWS file below or look at Romain’s blog where he highlights named-based in...

U of C ACM talk
Fellow GSoC mentor and local ACM masterminder Borja Sotomayor had invited me a few months ago to give a talk at the ACM chapter at the University of Chicago. Today was the day, and the slides from the 50-minutes talk on R and extending R with Rcpp are now on my presentations page. Related To leave a comment for the author, please follow the l...

R and Sudoku solvers: Plus ca change…
Christian Robert blogged about a particularly heavy-handed solution to last Sunday’s Sudoku puzzle in Le Monde. That had my symapthy as I like evolutionary computing methods, and his chart is rather pretty. From there, this spread on to the REvolutions blogs where David Smith riffed on it, and showed the acual puzzle. That didn’t stop thing...

Rcpp 0.7.8
Version 0.7.8 of the Rcpp R / C++ interface classes is now on CRAN and in Debian. As of right now. Debian has already built packages for eight more architectures; and CRAN has built the Windows binary. Oh, and cran2deb had Debian packages for ‘testing’ before I was done with the blog entry. This is a minor feature release based on a over th...

RcppExamples 0.1.0
Version 0.1.0 of RcppExamples, a simple demo package for Rcpp should appear on CRAN some time tomorrow. As mentioned in the post about release 0.7.8 of Rcpp, Romain and I carved this out of Rcpp itself to provide a cleaner separation of code that implements our R / C++ interfaces (which remain in Rcpp) and code that illustrates how to use...

RcppArmadillo 0.1.0
Besides the new RcppExamples, another new package RcppArmadillo got spun out of Rcpp with the recent release 0.7.8 of Rcpp. Romain and I already had an example of a simple but fast linear model fit using the (very clever) Armadillo C++ library by Conrad Sanderson. In fact, I had used this as a motivational example of why Rcpp rocks in a recen...

Rcpp 0.7.9
Version 0.7.8 of Rcpp, released just a few days ago contained a nasty bug or two which we noticed when trying to built the initial release of RcppArmadillo on 64-bit platforms. So a quick bug-fix release 0.7.9 is now in Debian and should be on CRAN shortly. The full NEWS entry for this release follows: 0.7.9 2010-03-12 o Another small ...

Rcpp 0.7.10
Versions 0.7.7 to 0.7.9 of Rcpp contained a bug: protecting paths with quotes was supposed to help with Windows builds, but did the opposite at least in ‘backticks mode’ for getting path and/or library information. Using the shQuote() function instead helped. Our thanks to the tireless R-on-Windows maintainer Uwe Ligges for an earlier heads-u...

Earlier today, Google announced the list of accepted mentor organizations for the Google Summer of Code 2010 (GSoC 2010). And we are happy to report that the R Project is once again a participating organization (and now for the third straight year) joining a rather august group of open source projects from around the globe. An R Wiki page had be...
