Why You Should Vectorize Your Code in R

Using the microbenchmark package in R to compare the efficiency between vectorized operations and for-loops

In this article, I will illustrate the benefits of using vectorized code by comparing how long it takes to perform three different tasks using vectorized operations versus using a for-loop for the same task. The microbenchmark package in R provides a handy tool to compare how long different R expressions take to execute.
