A new and much enhanced version of RcppMsgPack arrived on CRAN a couple of days ago. It came together following this email to the r-package-devel list which made it apparent that Travers Ching had been working on MessagePack converters for R which re... [Read more...]

A new minor release of RcppRedis arrived on CRAN last week, following the release 0.2.0 of RcppMsgPack which brought the MsgPack headers forward to release 2.1.5. This required a minor and rather trivial change in the code. When the optional RcppMsgP... [Read more...]

An new version 0.0.9 of RcppAnnoy, our Rcpp-based R integration of the nifty Annoy library by Erik, is now on CRAN. Annoy is a small and lightweight C++ template header library for very fast approximate nearest neighbours. This release corrects an is... [Read more...]

A second fix-up release is needed following on the recent bi-monthly RcppArmadillo release as well as the initial follow-up as it turns out that OS X / macOS is so darn special that it needs an entire separate treatment for OpenMP. Namely to turn it... [Read more...]

A new version 0.2.0 of the RcppSMC package arrived on CRAN earlier today (as a very quick pretest-publish within minutes of submission). RcppSMC provides Rcpp-based bindings to R for the Sequential Monte Carlo Template Classes (SMCTC) by Adam Johanse... [Read more...]

The BH package on CRAN was updated today to version 1.65.0. BH provides a sizeable portion of the Boost C++ libraries as a set of template headers for use by R, possibly with Rcpp as well as other packages. This release upgrades the version of Boost ... [Read more...]

Over the last few days, Rcpp passed another noteworthy hurdle. It is now used by over 10 percent of packages on CRAN (as measured by Depends, Imports and LinkingTo, but excluding Suggests). As of this morning 1130 packages use Rcpp out of a total of... [Read more...]

On the heels of the very recent bi-monthly RcppArmadillo release comes a quick bug-fix release 0.7.960.1.1 which just got onto CRAN (and I will ship a build to Debian in a moment). There were three distinct issues I addressed in three quick pull req... [Read more...]

Welcome to the tenth post in the rarely ranting R recommendations series, or R4 for short. A few days ago we showed how to tell the linker to strip shared libraries. As discussed in the post, there are two options. One can either set up ~/.R/Makevars by passing the ... [Read more...]

The bi-monthly RcppArmadillo release is out with a new version 0.7.960.1.0 which is now on CRAN, and will get to Debian in due course. And it is a big one. Lots of nice upstream changes from Armadillo, and lots of work on our end as the Google Summe... [Read more...]

Welcome to the nineth post in the recognisably rancid R randomness series, or R4 for short. Following on the heels of last week's post, we aim to look into the shared libraries created by R. We love the R build process. It is robust, cross-platform, reliable and rather predicatable. It. ... [Read more...]

RProtoBuf provides R bindings for the Google Protocol Buffers ("ProtoBuf") data encoding and serialization library used and released by Google, and deployed fairly widely in numerous projects as a language and operating-system agnostic protocol. A new releases RProtoBuf 0.4.10 just appeared on CRAN. It is a maintenance releases replacing one leftover ... [Read more...]

Welcome to the eight post in the ramblingly random R rants series, or R4 for short. We took a short break over the last few weeks due to some conferencing followed by some vacationing and general chill. But we're back now, and this post gets us back to initial spirit ... [Read more...]

Just getting back from the most fun meetup I have been to in quite some time: episode 23 (by their count) of Open Source Open Mic hosted by Matt Godbolt and Joe Walnes here in Chicago. Nothing but a sequence of lightning talks. Plus beer and pizza. S... [Read more...]

A good six years ago I blogged about plotOBOS() which charts a moving average (from one of several available variants) along with shaded standard deviation bands. That post has a bit more background on the why/how and motivation, but as a teaser here is the resulting chart of the ... [Read more...]

A new version of RcppAPT -- our interface from R to the C++ library behind the awesome apt, apt-get, apt-cache, ... commands and their cache powering Debian, Ubuntu and the like -- arrived on CRAN yesterday. We added a few more functions in order to ... [Read more...]

The twelveth update in the 0.12.* series of Rcpp landed on CRAN this morning, following two days of testing at CRAN preceded by five full reverse-depends checks we did (and which are always logged in this GitHub repo). The Debian package has been built and uploaded; Windows and macOS binaries should ... [Read more...]

A new version of the nanotime package for working with nanosecond timestamps just arrived on CRAN. nanotime uses the RcppCCTZ package for (efficient) high(er) resolution time parsing and formatting up to nanosecond resolution, and the bit64 package for the actual integer64 arithmetic. Thanks to a metric ton of work ... [Read more...]
