Welcome to the 22nd post in the reasonably rational R recommendations series, or R4 for short.
This post premieres something new: a matching video in lightning talk style:
The topic is something we had mentioned a few times before in this r^4 blog series, for example in this post on finding deb packages as well as in this post on binary installations. Binaries rocks, where available, and Michael Rutter’s PPAs should really be known and used more widely. Hence the video and supporting slides.
littler is the first command-line interface for R and predates
Rscript. And it is (in my very biased eyes) better as it allows for piping as well for shebang scripting via
#!, uses command-line arguments more consistently and still starts faster. It also always loaded the
methods package which
Rscript converted to only more recently.
littler lives on Linux and Unix, has its difficulties on macOS due to yet-another-braindeadedness there (who ever thought case-insensitive filesystems as a default where a good idea?) and simply does not exist on Windows (yet – the build system could be extended – see RInside for an existence proof, and volunteers are welcome!). See the FAQ vignette on how to add it to your
This release extends the support for
options("Ncpus") to the scripts
install2.r (which has
docopt support) making installation of CRAN packages proceed in parallel and thus quite a bit faster. We also added a new script to run tests from the excellent tinytest package, made the
rhub checking scripts more robust to the somewhat incomplete latex support there, and updated some documentation.
NEWS file entry is below.
Changes in littler version 0.3.8 (2019-06-09)
Changes in examples
The install.r and install2.r scripts now use parallel installation using
options("Ncpu")on remote packages.
install.rscript has an expanded help text mentioning the environment variables it considers.
A new script
tt.twas added to support tinytest.
The rhub checking scripts now all suppress builds of manual and vignettes as asking for working latex appears to be too much.
Changes in package
- On startup checks if r is in PATH and if not references new FAQ entry; text from Makevars mentions it too.
Changes in documentation
- The FAQ vignette now details setting r to PATH.
CRANberries provides a comparison to the previous release. Full details for the littler release are provided as usual at the ChangeLog page. The code is available via the GitHub repo, from tarballs and now of course all from its CRAN page and via
install.packages("littler"). Binary packages are available directly in Debian as well as soon via Ubuntu binaries at CRAN thanks to the tireless Michael Rutter.
