function

calculate_something  <- function(       ) {
  # do something

When is OOP a good idea?

Summary

• With functional programming, think about the functions first.
• With object-oriented programming (OOP) think about the data structures first.
• Don't use OOP for general purpose data analyses.
• Do use OOP when you have a limited number of complex objects.

Let's practice!
