Learning to Modify Factor Levels in R with dplyr::mutate()

Introduction to Factor Level Manipulation in R When conducting data analysis in R, managing factor variables is a foundational skill. Factors are specialized data structures that are integral to representing categorical data, such as survey responses, geographical regions, or experimental groups. Unlike simple character strings, factors are stored internally as integer vectors, where each integer
