Course Description

How can you reuse R code to avoid introducing bugs? How can you reuse R code without introducing inefficiencies in a serial loop? The R programming language has basic control flow like many other programming languages, which combined with functional programming concepts allows for modular code design. The R programming language also allows for vectorization and vectorized loop functions designed to parallelize operations to scale with data size and available computing resources. Learning how to use the best looping and vectorizing techniques is an essential skill for any R programmer, especially for large data processing projects. The topics discussed in this course will provide you with a solid foundation for writing scalable R code.

In these lessons, you will learn control flow in R, especially loops and loop-=like programming. We will explore conditional loops, structural loops, and conditional quitting. We will also discuss vectorizing functions and applying loop functions in order to avoid structural loops in R. By the end of these lessons, you will be able to write loops or use loop-like techniques to apply R functions for data processing tasks.

What You'll Learn

  • Understand conditional loops, structural loops, and conditional quitting in R
  • Explain when a loop is necessary and when it can be avoided
  • Apply best practices for writing loops and loop-like functions in R
  • Use vectorized and matrix operations to avoid structural loops
  • Apply loop functions and split-and-apply techniques for data processing
  • Write loops or loop-like techniques to apply R functions to data processing tasks
