Selecting columns

• everything() for all non-grouping columns
• where() to select based on a condition
  • where(is.numeric) = all numeric columns
  • where(is.character) = all character columns
  • starts_with("a") & !where(is_numeric) = all columns that start with “a” and are not numeric
  • where(\(x) any(stringr::str_detect("name"))) = all columns that contain the word “name” in at least one value
