Use the coalesce() Function in dplyr (With Examples)

Introduction to coalesce() in dplyr When working with real-world data in R programming, encountering missing values is not just common—it is inevitable. These gaps in data, typically represented by the constant NA (Not Available), pose a significant challenge to data integrity and can potentially skew analytical results if not addressed systematically. Fortunately, the widely adopted […]
