Function addClass()

The function addClass adds an element to the class attribute of an object. You may never have heard about the class attribute. That’s ok. It allows you to assign a user-defined class to an object. By doing so, you can do some nice stuff, for example:

# Define your own print function for objects of class "birthday"
print.birthday <- function(x) {
  print(sprintf("It's your birthday: %s!", x))
}

# Define a birthday string and print it
x <- "January 14"
print(x)
#> [1] "January 14"

# Now, set the class attribute to "birthday" and print again!
x <- kwb.utils::addClass(x, "birthday")
print(x)
#> [1] "It's your birthday: January 14!"
