R Programming: Control Flow, Functions, and Iteration

Moving beyond basic data manipulation in R requires understanding how to automate repetitive tasks and structure your code logically. This text-based course guides you through core programmatic concepts in R, helping you transition from writing simple scripts to designing modular, robust data analysis workflows. You will build a thorough understanding of conditional execution, loop structures, and functional programming patterns while learning when to favor vectorization for optimal performance. What you'll learn: - Master logical operators, relational comparisons, and conditional statements to control code execution - Write and debug custom functions with clear arguments, default values, and scoping rules - Apply traditional iteration using for loops and while loops for sequential tasks - Understand vectorization and performance trade-offs in data processing - Implement modern functional programming workflows using map functions and list-columns - Practice error handling and defensive coding strategies to build reliable analytical scripts The course begins with foundational terminology and control flow mechanics before progressing into modular function creation, iteration strategies, and automated data workflows through clear written explanations and practical code examples. This course is designed for learners with basic familiarity with R syntax who want to write more structured and maintainable code without needing advanced programming experience.
