What you will learn

• Implement conditional program logic using if-else structures, nested conditional statements, `is` functions, and the `%in%` membership operator.

• Control execution flow with for and while loops alongside functional vectorized loop alternatives like `apply()`, `lapply()`, and `sapply()`.

• Structure reusable code by defining custom functions with dynamic scope, lazy evaluation rules, and flexible ellipsis `(...)` arguments.

• Data files for this course are provided in the first course of this specialization, "R Programming: Setup and Data Processing".
