rOpenSci’s second cohort of Champions has been onboarded! Their training first started with a session on code style, was followed by three sessions on the basics of R package development, and ended with a session on advanced R package development, which consisted of a potpourri of tips with discussion, followed by time for applying these principles to the participants’ packages. Here, I want to share one of the topics covered: Package testing, and in particular, the DRY (“don’t repeat yourself”) and DAMP (“descriptive and meaningful phrases”) principles. For this topic, we used a GitHub repository, containing an R package whose different commits illustrate the two principles. In each step we’ll share a commit or diff illustrating the changes made.

A lightweight service for creating map tiles from Cloud-Optimized GeoTiff

First things first; let’s try to understand what a terrain is. A terrain represents the physical features of an area of land. It includes elevation, slope and the arrangement of the natural features such as mountains, plains and rivers. A terrain influences the natural features such as how the inhabitants of a particular area carry...

Batch processing framework for 'ellmer' chat models. Provides both sequential and parallel processing of chat interactions with features including tool calling and structured data extraction. Enables workflow management through progress tracking and recovery and automatic retry with backoff. Additional quality-of-life features include verbosity (or echo) control and sound notifications. Parallel processing is implemented via the 'future' framework. Includes methods for retrieving progress status, chat texts, and chat objects.
