Feed: R-bloggers. Author: Thinking inside the box. Overview R 3.5.0 was released a few weeks ago. As it changes some (important) internals, packages installed with a previous version of R have to be rebuilt. This was known and expected, and we took several measured steps to get R binaries to everybody without breakage. The question of but how do I upgrade without breaking my system was asked a few times, e.g., on the r-sig-debian list as well as in this StackOverflow question. Debian Core Distribution As usual, we packaged R 3.5.0 as soon as it was released – but only ... Read More

Feed: R-bloggers. Author: Thinking inside the box. A maintenance release 0.1.5 of RcppZiggurat is now on the CRAN network for R. The RcppZiggurat package updates the code for the Ziggurat generator which provides very fast draws from a Normal distribution. The package provides a simple C++ wrapper class for the generator improving on the very basic macros, and permits comparison among several existing Ziggurat implementations. This can be seen in the figure where Ziggurat from this package dominates accessing the implementations from the GSL, QuantLib and Gretl—all of which are still way faster than the default Normal generator in R ...

Feed: R-bloggers. Author: Thinking inside the box. A maintenance update 0.3.6 of RcppGSL is now on CRAN. The RcppGSL package provides an interface from R to the GNU GSL using the Rcpp package. Per a request from CRAN, we changed the vignette to accomodate pandoc 2.* just as we did with the most recent pinp release two days ago. No other changes were made. The (this time really boring) NEWS file entry follows: Changes in version 0.3.6 (2018-06-10) The vignette was updated to accomodate pandoc 2* [CRAN request]. Courtesy of CRANberries, a summary of changes to the most recent release ... Read More

Feed: R-bloggers. Author: Thinking inside the box. A maintenance release RcppClassic 0.9.9 is now at CRAN. This package provides a maintained version of the otherwise deprecated first Rcpp API; no new projects should use it. Per a request from CRAN, we changed the vignette to accomodate pandoc 2.* just as we did with the most recent pinp release two days ago. No other changes were made. CRANberries also reports the changes relative to the previous release. Questions, comments etc should go to the rcpp-devel mailing list off the R-Forge page. This post by Dirk Eddelbuettel originated on his Thinking inside ... Read More

Feed: R-bloggers. Author: Thinking inside the box. Another maintenance release, now at version 0.1.6, of our RcppDE package is now on CRAN. It follows the most recent (unblogged, my bad) 0.1.5 release in January 2016 and the 0.1.4 release in September 2015. RcppDE is a "port" of DEoptim, a popular package for derivative-free optimisation using differential evolution optimization, to C++. By using RcppArmadillo, the code becomes a lot shorter and more legible. Our other main contribution is to leverage some of the excellence we get for free from using Rcpp, in particular the ability to optimise user-supplied compiled objective functions ... Read More

Feed: R-bloggers. Author: Thinking inside the box. Another maintenance release of our pinp package for snazzier one or two column vignettes is getting onto CRAN right now. Everybody’s favourite Swiss Army Knife of text processing and document conversion, pandoc, decided in all its wisdow for version 2.* to no longer allow an idiom of embedding full LaTeX chunks in the Markdown YAML header. We had used this in our own package vignette to include the processed references (i.e., what BibTeX generates given input and style file). So this has been moved to a file that will be included. As most ... Read More

Feed: R-bloggers. Author: Thinking inside the box. Another bi-monthly update and the seventeenth release in the 0.12.* series of Rcpp landed on CRAN late on Friday following nine (!!) days in gestation in the incoming/ directory of CRAN. And no complaints: we just wish CRAN were a little more forthcoming with what is happenening when, and/or would let us help supplying additional test information. I do run a fairly insane amount of backtests prior to releases, only to then have to wait another week or more is … not ideal. But again, we all owe CRAN and immense amount of ... Read More

Feed: R-bloggers. Author: Thinking inside the box. A maintenance update of RcppGSL just brought version 0.3.5 to CRAN, a mere twelve days after the RcppGSL 0.3.4. release. Just like yesterday’s upload of inline 0.3.15 it was prompted by a CRAN request to update the per-package manual page; see the inline post for details. The RcppGSL package provides an interface from R to the GNU GSL using the Rcpp package. No user-facing new code or features were added. The NEWS file entries follow below: Changes in version 0.3.5 (2018-05-19) Update package manual page using references to DESCRIPTION file [CRAN request]. Courtesy ... Read More

Feed: R-bloggers. Author: Thinking inside the box. A maintenance release of the inline package arrived on CRAN today. inline facilitates writing code in-line in simple string expressions or short files. The package is mature and in maintenance mode: Rcpp used it greatly for several years but then moved on to Rcpp Attributes so we have a much limited need for extensions to inline. But a number of other package have a hard dependence on it, so we do of course look after it as part of the open source social contract (which is a name I just made up, but ... Read More

Feed: R-bloggers. Author: Thinking inside the box. A minor update version 0.3.4 of RcppGSL is now on CRAN. It contains an improved Windows build system (thanks, Jeroen!) and updates the C++ headers by removing dynamic exception specifications which C++11 frowns upon, and the compilers lets us know that in no uncertain terms. Builds using RcppGSL will now be more quiet. And as always, an extra treat for Solaris. The RcppGSL package provides an interface from R to the GNU GSL using the Rcpp package. No user-facing new code or features were added. The NEWS file entries follow below: Changes in ... Read More
