SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps R developers navigate the complexities of object-oriented programming in R, enabling them to choose the right OOP system (S7, S3, S4, vctrs) for their project and implement it effectively.

Core Features & Use Cases

OOP System Selection: Provides a decision tree to guide the choice between S7, S3, S4, and vctrs based on project needs.
Class Design: Offers practical guidelines and examples for designing classes using S7, S3, and vctrs.
Migration Strategies: Outlines approaches for migrating between different R OOP systems.
Use Case: When starting a new R package that requires robust data structures, this Skill will help you decide whether to use S7 for its formal structure and validation, or vctrs for vector-like behavior.

Quick Start

Use the designing-oop-r skill to understand when to choose S7 over S3 for new R projects.

FAQPage Schema

How do I choose the right OOP system in R for my package?▼

Choosing the right OOP system in R depends on your project needs, using a decision tree to select between S7, S3, S4, and vctrs for robust and maintainable package development.

When should I use S7 instead of S3 for class design in R?▼

Use S7 instead of S3 when your R project requires formal class structure and validation, while S3 is suitable for simpler, more flexible object-oriented programming needs.

What is the best way to migrate between S4 and S3 OOP systems in R?▼

The best way to migrate between R OOP systems like S4 and S3 involves following specific migration strategies outlined to ensure robust data structures and maintain method dispatch correctly.

How do I implement vector-like behavior using vctrs in R?▼

Implement vector-like behavior in R using vctrs by following practical class design guidelines and examples to build robust data structures for your specific package requirements.

Does vctrs support formal method dispatch like S4 and S7?▼

vctrs focuses on vector-like behavior rather than the formal method dispatch and validation structures provided by S4 and S7, making it distinct for R class design.
