A maintenance release 0.1.1 of pkgKitten is now on CRAN. It has only one small change: the function playWithPerPackageHelpPage() was factored out of the main function kitten() as I happened to be needing something just like playWithPerPackageHelpPage... [Read more...]

With yesterday's announcement of littler 0.2.0, I kept thinking about a few not-so-frequently-asked but recurring questions about littler. And an obvious one if of course the relationship to Rscript. As we have pointed out before, littler preceded Rscript. Now, with Rscript being present in every R installation, it is of course ... [Read more...]

After two pre-releases in the last few days, Conrad finalised a new Armadillo version 4.400 today. I had kept up with the pre-releases, tested twice against all eighty (!!) CRAN dependents of RcppArmadillo and have hence uploaded RcppArmadillo 0.4.... [Read more...]

A common theme over the last few decades was that we could afford to simply sit back and let computer (hardware) engineers take care of increases in computing speed thanks to Moore's law. That same line of thought now frequently points out that we ar... [Read more...]

While I was out at the (immensely impressive and equally enjoyable) useR! 2014 conference at UCLA, Conrad provided a bug-fix release 4.320 of Armadillo, the nifty templated C++ library for linear algebra. I quickly rolled that into RcppArmadillo rel... [Read more...]

A new package pkgKitten is now on CRAN in its infant version 0.1.0. It does only one thing: create R packages that do not suck. Or at least not as much as those created by the (R default) function package.skeleton() which creates files which the v... [Read more...]

A few days ago, version 0.2.1 of RcppGSL---our interface package between R and the GNU GSL using our Rcpp package for seamless R and C++ integration---appeared on CRAN making it the first release in some time. And it turned that this version tickle... [Read more...]
