Code chunks and output in R Programming - Mini Project: Build & Apply

Code chunks and output

📖 Scenario: You are learning how to write and run code chunks in R. This is useful when you want to organize your code and see the results step by step.

🎯 Goal: You will create a simple R script with code chunks that assign values, perform calculations, and print the results.

📋 What You'll Learn

Create a variable with a specific value

Create a helper variable for calculation

Use a code chunk to perform a calculation

Print the final result

💡 Why This Matters

🌍 Real World

Organizing code into chunks helps you write clear and easy-to-follow scripts for data analysis or reports.

💼 Career

Many data jobs require writing clean R code that shows intermediate results clearly for collaboration and debugging.

1

Create a variable called number and assign it the value 10

Write a line of R code to create a variable called number and set it equal to 10.

R Programming

# Create a variable called number and assign 10
# Your code here

Need a hint?

Use the assignment operator <- to assign the value.

2

Create a variable called multiplier and assign it the value 5

Write a line of R code to create a variable called multiplier and set it equal to 5.

R Programming

number <- 10
# Create a variable called multiplier and assign 5
# Your code here

Need a hint?

Use the assignment operator <- again to assign the value.

3

Create a variable called result that multiplies number by multiplier

Write a line of R code to create a variable called result and set it equal to number multiplied by multiplier.

R Programming

number <- 10
multiplier <- 5
# Create a variable called result that multiplies number by multiplier
# Your code here

Need a hint?

Use the * operator to multiply the two variables.

4

Print the value of result

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

R Programming

number <- 10
multiplier <- 5
result <- number * multiplier
# Print the value of result
# Your code here

Need a hint?

Use the print() function to display the value.
