if … else This is how you tell the computer: “If this condition is true → do this, otherwise → do that.” It’s used everywhere: Decide whether to show a warning Apply different calculations...

Part 1: What Are Nested If Statements? A nested if statement is simply an if statement placed inside another if statement. It allows you to test multiple conditions in a hierarchical way, where the inner condition is only evaluated if...

Part 1: The Core Operators – What They Are In R, we have two main types of logical operators: element-wise and single-value operators. Let’s start with the basics. The AND Operators & (Element-wise AND) – Compares each corresponding element of...

Part 1: What is a While Loop? A while loop repeatedly executes a block of code as long as a specified condition remains TRUE. Once the condition becomes FALSE, the loop stops and the program continues...

Part 1: What is a For Loop? A for loop is a control structure that repeats a block of code for each element in a sequence or collection. It’s called a “for” loop because it runs...

Part 1: What Are Nested Loops? A nested loop is simply a loop inside another loop. For each iteration of the outer loop, the inner loop runs completely from start to finish. The Basic Structure r...

Part 1: What is a Function? A function is a self-contained block of code that performs a specific task. It can take inputs (called arguments), process them, and return an output. Why Use Functions? Reusability: Write once,...

Part 1: What Are Nested Functions? A nested function is simply a function defined inside another function. The inner function is only visible and accessible within the outer function, creating a private workspace that can’t be...

Part 1: What is Recursion? Recursion is a programming technique where a function calls itself to solve a problem by breaking it down into smaller instances of the same problem. The Two Essential Parts of...

Part 1: What are Global Variables? Global variables are variables that are defined outside of any function and are accessible from anywhere in your R environment – including inside functions, loops, and other structures. The...
