Comparison operators in R Programming - Mini Project: Build & Apply

Comparison Operators in R

📖 Scenario: You are working in a small shop and want to check which products are priced above a certain amount to decide which ones to promote.

🎯 Goal: Build a simple R program that uses comparison operators to find products priced above a threshold.

📋 What You'll Learn

Create a named numeric vector called products with exact product names and prices

Create a numeric variable called threshold with the value 50

Use a comparison operator to create a logical vector called expensive_products that is TRUE for products priced above threshold

Print the expensive_products vector

💡 Why This Matters

🌍 Real World

Shops often need to filter products by price to decide which items to promote or discount.

💼 Career

Understanding comparison operators is essential for data filtering and decision making in data analysis and programming jobs.

1

Create the products vector

Create a named numeric vector called products with these exact entries: apple = 30, banana = 20, cherry = 60, date = 80, elderberry = 40.

R Programming

# Create the products vector with exact names and prices
# Your code here

Need a hint?

Use the c() function with named elements like name = value.

2

Set the price threshold

Create a numeric variable called threshold and set it to 50.

R Programming

products <- c(apple = 30, banana = 20, cherry = 60, date = 80, elderberry = 40)
# Create the threshold variable and set it to 50
# Your code here

Need a hint?

Just assign the number 50 to the variable threshold.

3

Find products priced above the threshold

Use the greater than operator > to create a logical vector called expensive_products that is TRUE for products priced above threshold.

R Programming

products  with threshold
# Your code here

Need a hint?

Use products > threshold to get TRUE or FALSE for each product.

4

Print the result

Print the expensive_products vector to see which products are above the threshold.

R Programming

products  threshold
# Print expensive_products
# Your code here

Need a hint?

Use print(expensive_products) to show the logical vector.
