pubchunks is a package grown out of the fulltext package. fulltext provides a single interface to many sources of full text scholarly articles. As part of the user flow in fulltext there is an extraction step where fulltext::chunks() pulls parts of articles out of XML format article files. As part of making fulltext more maintainable and focused on simply fetching articles, and realizing that pulling out bits of structured XML files is a more general problem, we broke out pubchunks into a separate package....
Every R package has its story. Some packages are written by experts, some by novices. Some are developed quickly, others were long in the making. This is the story of jstor, a package which I developed during my time as a student of sociology, working in a research project on the scientific elite within sociology. Writing the package has taught me many things (more on that later) and it is deeply gratifying to see, that others find the package useful....
Proper identification of individuals is crucial for acknowledging and studying their scientific work, be it journal articles or pieces of software. In this tech note, one year after CRAN started supporting ORCIDs, we shall explain why and how to use unique author identifiers in DESCRIPTION files. 🔗 Why use ORCIDs on CRAN? When analyzing the authorship of CRAN packages, one can look at authorsā names and email addresses. Names can be written with and without quotes, email addresses change, which makes it all tricky as noted by David Smith when he looked for the most prolific CRAN authors (notice our very own Scott Chamberlain and Jeroen Ooms in that scoreboard by the way?...
At rOpenSci we are developing on a suite of packages that expose powerful graphics and imaging libraries in R. Our latest addition is av – a new package for working with audio/video based on the FFmpeg AV libraries. This ambitious new project will become the video counterpart of the magick package which we use for working with images. install.packages("av") av::av_demo() The package can be installed directly from CRAN and includes a test function av_demo() which generates a demo video from random histograms....
