Thomas Lin Pedersen - API-first package design — and learning patchwork in the process

Data visualisation frameworks have an inherent need for good API design in order to be effective due to the potential for unbounded features their creative problem space holds. This talk will go through some of the ways taking an API-first approach to package development can play out, drawing on the experience of developing and maintaining the patchwork package over many years. Through the talk, the audience will also get an introduction to the use of patchwork, a package designed to make it effortless to combine multiple plots into a single composite figure.

Thomas Lin Pedersen | Extending your ability to extend ggplot2 | RStudio (2020)

The ggplot2 package continue to be one of the most used frameworks for producing graphics in R. While being extremely flexible, the package itself can be constrained by the different types of graphic elements and statistic transformations available. Instead of continuing to add new features, the development in recent years have focused on making ggplot2 extensible by other packages, thus distributing development and maintenance. Despite the best of intentions, ggplot2 can feel daunting to extend, due unusual idiosyncrasies, a foreign object system, and a partly obscured rendering model. This talk intend to remove the mystery of extending ggplot2, by describing the basic ways that it can be extended and showcasing a couple of simple extensions that can be build with very little code. Lastly, it will include discussions of some best practices and gotchas that may come in handy when you start out
