If-else statements in R Programming - Mini Project: Build & Apply

If-else statements

📖 Scenario: You are helping a small shop owner decide if a product is affordable for customers based on its price.

🎯 Goal: Build a simple R program that uses if-else statements to check if a product price is affordable or expensive compared to a set budget.

📋 What You'll Learn

Create a variable with the product price

Create a variable with the budget limit

Use an if-else statement to compare the price with the budget

Print 'Affordable' if the price is less than or equal to the budget

Print 'Expensive' if the price is greater than the budget

💡 Why This Matters

🌍 Real World

Shop owners often need to check if product prices fit within customer budgets to decide promotions or discounts.

💼 Career

Understanding if-else statements is essential for programming logic used in data analysis, automation, and decision-making tasks.

1

Create the product price variable

Create a variable called price and set it to 120.

R Programming

# Create a variable called price and set it to 120
# Your code here

Need a hint?

Use the assignment operator <- to assign the value 120 to price.

2

Create the budget variable

Create a variable called budget and set it to 100.

R Programming

price <- 120
# Create a variable called budget and set it to 100
# Your code here

Need a hint?

Use the assignment operator <- to assign the value 100 to budget.

3

Write the if-else statement

Write an if-else statement that checks if price is less than or equal to budget. If yes, assign the string 'Affordable' to a variable called result. Otherwise, assign 'Expensive' to result.

R Programming

price <- 120
budget <- 100
# Write an if-else statement to set result based on price and budget
# Your code here

Need a hint?

Use if (price <= budget) { ... } else { ... } to decide the value of result.

4

Print the result

Write a line to print the value of the variable result.

R Programming

price <- 120
budget <- 100
if (price <= budget) {
  result <- 'Affordable'
} else {
  result <- 'Expensive'
}
# Print the result variable
# Your code here

Need a hint?

Use print(result) to show the result on the screen.
