Other purrr function operators

purrr comes with three other function operators in a similar vein:

  possibly(): returns a default value when there’s an error. It provides no way to tell if an error occured or not, so it’s best reserved for cases when there’s some obvious sentinel value (like NA).

  quietly(): turns output, messages, and warning side-effects into output, message, and warning components of the output.

  auto_browser(): automatically executes browser() inside the function when there’s an error.
