notary - Signing & Verification of R Packages

  Rich FitzJohn   |   Oliver Keyes   |   Stephanie Locke   |   Jeroen Ooms   |   Bob Rudis   | JULY 25, 2017

Most of us who work in R just want to Get Stuff Done™. We want a minimum amount of friction between ourselves and the data we need to wrangle, analyze, and visualize. We’re focused on solving a problem or gaining insights into a new area of research. We rely on a rich, community-driven ecosystem of packages to help get our work done and likely make an unconscious assumption that there is a safety net out there, protecting us from harm.

Advanced Image-Processing in R with Magick, Part I

  Jeroen Ooms   | AUGUST 23, 2016

The new magick package is an ambitious effort to modernize and simplify high-quality image processing in R. It wraps the ImageMagick STL which is perhaps the most comprehensive open-source image processing library available today. The ImageMagick library has an overwhelming amount of functionality. The current version of Magick exposes a decent chunk of it, but being a first release, documentation is still sparse. This post briefly introduces the most important concepts to get started.

Testing packages with R Travis for OS-X

  Jeroen Ooms   | JULY 12, 2016

Travis is a continuous integration service which allows for running automated testing code everytime you push to GitHub. Hadley’s book about R packages explains how and why R package authors should take advantage of this in their development process. The build matrix Travis is now providing support for multiple operating systems, including Ubuntu 14.04 (Trusty) and various flavors of Mac OS-X. Jim Hester has done a great job of tweaking the travis R-language build script to automate building and checking of R packages on the various platforms.

Introducing pdftools - A fast and portable PDF extractor

  Jeroen Ooms   | MARCH 1, 2016

Scientific articles are typically locked away in PDF format, a format designed primarily for printing but not so great for searching or indexing. The new pdftools package allows for extracting text and metadata from pdf files in R. From the extracted plain-text one could find articles discussing a particular drug or species name, without having to rely on publishers providing metadata, or pay-walled search engines. The pdftools slightly overlaps with the Rpoppler package by Kurt Hornik.
