R Code Patterns for Packages

What problem does it solve?

This Skill addresses common pitfalls and best practices in R package development, ensuring code is robust, maintainable, and adheres to R's ecosystem standards.

Core Features & Use Cases

• Namespace Management: Guides on using pkg::fun() and @importFrom to manage dependencies correctly.
• Code Restrictions: Details forbidden functions (library(), source(), :::) and explains why they should be avoided in package code.
• State Management: Provides patterns for handling global state, options, and environments safely.
• Build vs. Load Time: Clarifies what code executes during package build versus when a user loads the package.
• Use Case: A developer is unsure how to properly import functions from other R packages into their own package. This skill provides clear examples and explanations on using explicit namespace calls and @importFrom directives.
