Modern R Development Guide

This document captures current best practices for R development, emphasizing modern tidyverse patterns, performance, and style. Last updated: August 2025

Core Principles

  1. Use modern tidyverse patterns - Prioritize dplyr 1.1+ features, native pipe, and current APIs
  2. Profile before optimizing - Use profvis and bench to identify real bottlenecks
  3. Write readable code first - Optimize only when necessary and after profiling
  4. Follow tidyverse style guide - Consistent naming, spacing, and structure
