RcppMsgPack 0.1.1
A new package! Or at least new on CRAN as the very initial version 0.1.0 had been available via the ghrr drat for over a year. But now we have version 0.1.1 to announce as a CRAN package. RcppMspPack provides R with MessagePack header files for use via C++ (or C, if you must) packages such as RcppRedis. MessagePack itself is an efficient binary s...

#7: C++14, R and Travis — A useful hack
Welcome to the seventh post in the rarely relevant R ramblings series, or R4 for short. We took a short break as several conferences and other events interfered during the month of May, keeping us busy and away from this series. But we are back now with a short and useful hack I came up with this weekend. The topic is C++14, i.e. the newest forma...

RcppCCTZ 0.2.3 (and 0.2.2)
A new minor version 0.2.3 of RcppCCTZ is now on CRAN. RcppCCTZ uses Rcpp to bring CCTZ to R. CCTZ is a C++ library for translating between absolute and civil times using the rules of a time zone. In fact, it is two libraries. One for dealing with civil time: human-readable dates and times, and one for converting between between absolute and civil...

nanotime 0.2.0
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 by Leonardo Silvestri, the pack...

Rcpp 0.12.12: Rounding some corners
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 follow at CRAN as usual. This 0.12.12 release f...

RcppAPT 0.0.4
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 compute on the package graph. A concrete example is shown in this vignette which determines the ...

Updated overbought/oversold plot function
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 SP500 index (with ticker ^GSCP): The code uses a few standard fina...

R for System Adminstration
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. Sounds awesome? It was! We had fantastic talks across at least half a dozen languages, covering bot...

#8: Customizing Spell Checks for R CMD check
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 of (hopefully) quick and useful posts. Perusing yesterday’s batch of CRANber...

A new releases RProtoBuf 0.4.10 just appeared on CRAN. It is a maintenance releases replacing one ...
