RQuantLib 0.4.12: Small QuantLib 1.18 update
A new release 0.4.12 of RQuantLib arrived on CRAN today, and was uploaded to Debian as well. QuantLib is a very comprehensice free/open-source library for quantitative finance; RQuantLib connects it to the R environment and language. This version does relatively little. When QuantLib 1.18 came out, I immediately did my usual bit of packaging it f...

RcppSimdJson 0.0.4: Even Faster Upstream!
A new (upstream) simdjson release was announced by Daniel Lemire earlier this week, and my Twitter mentions have been running red-hot ever since as he was kind enough to tag me. Do look at that blog post, there is some impressive work in there. We wrapped up the (still very simple) rcppsimdjson around it last night and shipped it this morning. Rc...

Rcpp 1.0.4.6: Bug fix interim version
Rcpp 1.0.4 was released on March 17, following the usual sequence of fairly involved reverse-depends check along with a call for community testing issued weeks before the release. In that email I specifically pleaded with folks to pretty-please test non-standard setups: It would be particularly beneficial if those with “unsual” build depende...

#24: Test, test, test, … those R 4.0.0 binaries with Ubuntu and Rocker
Welcome to the 24nd post in the relentlessly regular R ravings series, or R4 for short. R 4.0.0 will be released in less than two weeks, and testing is very important. I had uploaded two alpha release builds (at the end of March and a good week ago) as well as a first beta release yesterday, all to the Debian ‘experimental’ distribution (as y...

#25: Test, test, test, … those R 4.0.0 binaries with Ubuntu 20.04 and Rocker
Welcome to the 25nd post in the randomly recurring R recitations series, or R4 for short. Just yesterday, we posted a short post along with a video and supporting slides. It covered how to test the soon-to-be-released R 4.0.0 on a custom Ubuntu 18.04 Rocker container. A container for Ubuntu 20.04, which is itself in final beta stages, was being b...

gettz 0.0.4
A minor routine update 0.0.4 of gettz arrived on CRAN overnight. gettz provides a possible fallback in situations where Sys.timezone() fails to determine the system timezone. That happened when e.g. the file /etc/localtime somehow is not a link into the corresponding file with zoneinfo data in, say, /usr/share/zoneinfo. Since the package was writ...

RcppArmadillo 0.9.860.2.0
Armadillo is a powerful and expressive C++ template library for linear algebra aiming towards a good balance between speed and ease of use with a syntax deliberately close to a Matlab. RcppArmadillo integrates this library with the R environment and language–and is widely used by (currently) 706 other packages on CRAN. A new upstream release 9....

prrd 0.0.3: More improvements
Back in early 2018, the prrd package was introduced as release 0.0.1, uploaded to CRAN, and updated once as release 0.0.2. I have used it extensively for every CRAN release of Rcpp, RcppArmadillo, RcppEigen, BH, and possibly others. The idea of prrd is simple, and described in some more detail on its webpage and its GitHub repo. Reverse dependenc...

#26: Upgrading to R 4.0.0
Welcome to the 26th post in the rationally regularized R revelations series, or R4 for short. R 4.0.0 was released two days ago, and a casual glance at some social media conversations appears to suggest quite some confusion, almost certainly some misunderstandings, and possibly also a fair amount of fear, uncertainty, and doubt about the process....
