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

LLM for code generation

Currently three main styles:

1. Autocomplete
   • e.g. github copilot, windsurf
   • Inline "ghost text" as you type
   • Sometimes amazingly good; often pretty useless
   • Need to train yourself to ignore spurious suggestions

    vars:
      - name: "clipb"
        type: "clipboard"
