SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill provides a structured approach to creating type-stable vector operations and custom vector classes in R using the vctrs package, ensuring predictable behavior and seamless integration with data frames.

Core Features & Use Cases

  • Type and Size Stability: Guarantees consistent output types and sizes, preventing unexpected behavior.
  • Custom Vector Classes: Enables the creation of new vector types that work correctly with R's data structures.
  • Consistent Coercion: Implements predictable rules for converting between different data types.
  • Use Case: When developing an R package that requires custom data types (e.g., a 'percentage' type) that must behave predictably within data frames and functions.

Quick Start

Use the customizing-vectors-r skill to build a new custom vector class for R packages.

Frequently Asked Questions about customizing-vectors-r

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I create custom vector classes in R that work properly inside data frames?▼

Implement type-stable vector operations in R by using the vctrs package to define predictable output types and consistent coercion rules. This ensures your functions always return the expected class and length, preventing unexpected behavior during package development.

Why does my custom R vector type fail during type coercion?▼

Custom R vector types fail during coercion when explicit casting and coercion methods are not defined. Use the vctrs package to implement consistent coercion rules, ensuring predictable type conversion and robust S3 vector infrastructure for data frame compatibility.

When do I need to define explicit casting methods for R package development?▼

Define explicit casting methods during R package development when creating custom vector classes that require predictable output types. Using the vctrs package ensures consistent coercion rules and type stability for robust S3 vector infrastructure and data frame compatibility.

Can I use the vctrs package to build a percentage vector type in R?▼

Yes, use the vctrs package to build a custom percentage vector type in R. This enables type-stable vector operations, consistent coercion rules, and robust S3 vector infrastructure, ensuring the new class behaves predictably within data frames and functions.
