#' @title Create, modify, and delete columns

#' @description  This is a method for the [dplyr::mutate()] generic.
#' `mutate()` creates new columns that are functions of existing variables.
#' It can also modify (if the name is the same as an existing column)
#' and delete columns (by setting their value to `NULL`).
