Loops in R

Estimated time: 30 minutes

Overview

Questions

• How can I do the same thing multiple times more efficiently in R?
• What is vectorization?
• Should I use a loop or an apply statement?

Objectives

• understand loops types and create them
• identify and perform vectorized operations
• identify and understand when to use loops or vectorized operations

FIXME

Key Points

• loops consume computer resources and should be used sparingly
• R has vectorized operations to make classical looping operations faster
