Advanced R Programming

Welcome to Advanced R Programming

This course covers advanced topics in R programming that are necessary for developing powerful, robust, and reusable data science tools Topics covered include functional programming in R, robust error handling, object oriented programming, profiling and benchmarking, debugging, and proper design of functions Upon completing this course you will be able to identify and abstract common data analysis tasks and to encapsulate them in user-facing functions Because every data science environment encounters unique data challenges, there is always a need to develop custom software specific to your organization’s mission You will also be able to define new data types in R and to develop a universe of functionality specific to those data types to enable cleaner execution of data science tasks and stronger reusability within a team

Functions

This module begins with control structures in R for controlling the logical flow of an R program We then move on to functions, their role in R programming, and some guidelines for writing good functions

Functions: Lesson Choices

Functional Programming

Functional programming is a key aspect of R and is one of R's differentiating factors as a data analysis language Understanding the concepts of functional programming will help you to become a better data science software developer In addition, we cover error and exception handling in R for writing robust code

Functional Programming: Lesson Choices

Debugging and Profiling

Debugging tools are useful for analyzing your code when it exhibits unexpected behavior We go through the various debugging tools in R and how they can be used to identify problems in code Profiling tools allow you to see where your code spends its time and to optimize your code for maximum efficiency

Object-Oriented Programming

Object oriented programming allows you to define custom data types or classes and a set of functions for handling that data type in a way that you define R has a three different methods for implementing object oriented programming and we will cover them in this section
