Time for another update of RcppArmadillo with a new release 0.7.700.0.0 based on a fresh Armadillo 7.700.0. Following my full reverse-dependency check of 318 package (commit of log here), CRAN took another day to check again. Armadillo is a powerful and expressive C++ template library for linear algebra aiming towards a good balance ... [Read more...]

A pure maintenance release of the random package for truly (hardware-based) random numbers as provided by random.org is now on CRAN. As requested by CRAN, we made running tests optional. Not running tests is clearly one way of not getting (spurious, ... [Read more...]

A new minor version 0.2.1, of RcppCCTZ is now on CRAN. It corrects a possible shortcoming and rounding in the conversion from internal representation (in C++11 using int64_t) to the two double values for seconds and nanoseconds handed to R. Two other... [Read more...]

A new version of the nanotime package for working with nanosecond timestamps is now on CRAN. nanotime uses the RcppCCTZ package for (efficient) high(er) resolution time parsing and formatting, and the bit64 package for the actual integer64 arithmetic... [Read more...]

A major new update of the RPushbullet package is now on CRAN. RPushbullet interfacing the neat Pushbullet service for inter-device messaging, communication, and more. It lets you easily send alerts like the one to the to your browser, phone, tablet,... [Read more...]

An update to the gunsales package is now on the CRAN network. As in the last update, some changes are mostly internal. We removed the need to import two extra packages with were used in one line each -- easy enough to be replaced with base R. We also... [Read more...]

A new release, now at version 0.6.12, of the digest package is now on CRAN and in Debian. The digest creates hash digests of arbitrary R objects (using the 'md5', 'sha-1', 'sha-256', 'crc32', 'xxhash' and 'murmurhash' algorithms) permitting easy comp... [Read more...]

During useR! 2016, Nick Tierney had asked on Twitter about rmarkdown and metropolis and whether folks had used RMarkdown-driven LaTeX Beamer presentations. My firm hell yeah answer, based on having used mtheme outright or in local mods for quite some... [Read more...]

Issue ticket #20 demonstrated that we had not yet set up Windows for version 3 of Google Protocol Buffers ("Protobuf") -- while the other platforms support it. So I made the change, and there is release 0.4.8. RProtoBuf provides R bindings for the Google Protocol Buffers ("Protobuf") data encoding and serialization library used ... [Read more...]

Yesterday afternoon, the nineth update in the 0.12.* series of Rcpp made it to the CRAN network for GNU R. Windows binaries have by now been generated; and the package was updated in Debian too. This 0.12.9 release follows the 0.12.0 release from late July, the 0.12.1 release in September, the 0.12.2 release in November, ... [Read more...]

Last week, Josh sent the call for papers to the R-SIG-Finance list making everyone aware that we will have our nineth annual R/Finance conference in Chicago in May. Please see the call for paper (at the link, below, or at the website) and consider submitting a paper. We are ... [Read more...]

Last month, we released nanotime, a package to work with nanosecond timestamps. See the initial release announcement for some background material and a few first examples. nanotime relies on the RcppCCTZ package for high(er) resolution time parsing and formatting: R itself stops a little short of a microsecond. And ... [Read more...]

Today, Rcpp passed another milestone as 900 packages on CRAN now depend on it (as measured by Depends, Imports and LinkingTo declarations). The graph is on the left depicts the growth of Rcpp usage over time. The easiest way to compute this is to us... [Read more...]

A new version, now at 0.2.0, of RcppCCTZ is now on CRAN. And it brings a significant change: windows builds! Thanks to Dan Dillon who dug deep enough into the libc++ sources from LLVM to port the std::get_time() function that is missing from the 4.* ... [Read more...]

Big news: RcppTOML now works on Windows too! This package had an uneventful 2016 without a single update. Release 0.0.5 had come out in late 2015 and we had no bugs or issues to fix. We use the package daily in production: a key part of our parameterisation is in TOML files In ... [Read more...]

A new minor release with version number 0.6.11 of the digest package is now on CRAN and in Debian. It is mostly a maintenance release. Sometime last spring we were asked to consider changing the license GPL-2 to GPL (__= 2). Having gotten agreement... [Read more...]

A brand new anytime package just arrived at CRAN. This is release number eight, evenly spread with over two per month, since the initial release in September. Needless to say I have been told off not to make this many releases. As they say, no good deed goes unpunished. anytime ... [Read more...]

Earlier this week, Conrad released Armadillo 7.600.1. The corresponding RcppArmadillo release 0.7.600.1.0 is now on CRAN and in Debian. This follows several of rounds testing at our end with a full reverse-dependency of a pre-release version followe... [Read more...]

R has excellent tools for dates and times. The Date and POSIXct classes (as well as the 'wide' representation in POSIXlt) are versatile, and a lot of useful tooling has been built around them. However, POSIXct is implemented as a double with fractional seconds since the epoch. Given the 53 bits ... [Read more...]

Another update, now at release 0.1.2, of anytime arrived at CRAN earlier today. anytime is a very focused package aiming to do just one thing really well: to convert anything in integer, numeric, character, factor, ordered, ... format to either POSIXct or Date objects -- and to do so without requiring a ...
