课程描述

Object-oriented programming (OOP) lets you specify relationships between functions and the objects that they can act on, helping you manage complexity in your code. This is an intermediate level course, providing an introduction to OOP, using the S3 and R6 systems. S3 is a great day-to-day R programming tool that simplifies some of the functions that you write. R6 is especially useful for industry-specific analyses, working with web APIs, and building GUIs.

Using S3

S3 is a very simple object-oriented system that lets you define different behavior for functions, depending upon their input argument. This chapter explains how to use S3, and how generics and methods work.
