Conditional Logic in R with ifelse

Conditional decision-making is at the heart of all data manipulation and analysis. Understanding how to apply logic across entire datasets efficiently is a core skill for anyone working with data. This course helps you master the foundational concepts of conditional logic in R, focusing on the powerful and vectorized ifelse function. You will transition from writing basic, slow loops to executing fast, vectorized operations that handle missing values and complex logical structures with ease. By reading through clear explanations and studying practical code patterns, you will learn how to write clean, readable, and highly performant R code. What you'll learn: - Understand the core mechanics of vectorized conditional logic in R - Implement the ifelse function to transform and clean messy datasets - Handle missing values and NA cases safely within your conditional logic - Nest multiple conditional statements to solve complex decision-making problems - Apply modern best practices for code readability and performance optimization This course begins with essential programming concepts and basic logical operators before guiding you through practical data transformation scenarios. You will progress from simple binary choices to handling real-world data cleaning challenges. This course is designed for beginners who are familiar with basic R syntax and want to build a strong foundation in data manipulation. No advanced programming experience is required.
