RInside release 0.2.3
A new 0.2.3 release of RInside is now on CRAN. RInside is a set of convenience classes which facilitate embedding of R inside of C++ applications and programs. RInside works particularly well with Rcpp and now depends on it. This is the first release since March when we released 0.2.2. A few things got added to Rcpp in the meantime, and RIn...

RQuantLib 0.3.4
A fresh release of RQuantLib is now on CRAN and in Debian. RQuantLib combines (some of) the quantitative analytics of QuantLib with the R statistical computing environment and language. This follows the 0.3.3 release from last week and has again a number of internal changes. All uses of objects from external namespaces are now explicit as I ...

Louis: A Silent Film with Live Music
The Chicago Symphony hosted the world premiere of Louis last evening, and I had snatched the (literally) last available ticket. The film, which is written, directed and producted by Dan Pritzker, is based loosely on the early years of Louis Armstrong in New Orleans. The movie is shot beautifully by Vilmos Zsigmond in blend of colour and black-a...

Straight, curly, or compiled?
Christian Robert, whose blog I commented-on here once before, had followed up on a recent set of posts by Radford Neal which had appeared both on Radford’s blog and on the r-devel mailing list. Now, let me prefix this by saying that I really enjoyed Radford’s posts. He obviously put a lot of time into finding a number of (all somewhat small ...

Billy Bragg
In the spur of the moment, I cycled over to Dominican, one of the two small colleges in town, to see if I could snag a remaining ticket to see Billy Bragg perform. Turned out I could, and it became a nice evening out. Darren Hanlon started up the evening as the opener for a good half hour, and was quite decent; somewhat charming in a good nature...

RProtoBuf 0.2,0
A brand new and shiny release of RProtoBuf, now at version 0.2.0, arrived on CRAN earlier today. RProtoBuf provides GNU R bindings for the Google Protobuf data encoding library used and release by Google and others. This is only the second release after 0.1-0 more than six months ago. Given that Rcpp is such a key ingedrient for RProtoBuf,...

Now that Rcpp got updated to 0.8.6, we have an updated RcppArmadillo release containing mostly updates to Conrad’s Armadillo version 0.9.70 as well as some more templated sugar magic. RcppArmadillo makes it easy to write highly efficient and highly readable C++ code for linear algebra (based on Armadillo) in R extensions (using Rcpp for the i...

BLAS, BLASter, BLAStest: Some benchmark results, and a benchmarking framework
Usage of accelerated BLAS libraries seems to shrouded in some mystery, judging from somewhat regularly recurring requests for help on lists such as r-sig-hpc (gmane version), the R list dedicated to High-Performance Computing. Yet it doesn’t have to be; installation can be really simple (on appropriate systems). Another issue that I felt neede...
