Understanding dplyr Functions for Custom Data Manipulation and Column Creation
Understanding the Problem and Its Background The problem at hand revolves around data manipulation using the dplyr package, specifically with the mutate_each function. This function allows for the application of a custom function to each element in one or more columns of a data frame.
The given question presents an issue where the goal is to create new column names that correspond to specific values present in other column names. The problem arises when trying to use only a single funs function with multiple ifelse statements, which results in not creating additional columns as desired.
