Integer type in R Programming - Mini Project: Build & Apply

Integer type

📖 Scenario: You are working with numbers in R and want to understand how to create and use integer values.

🎯 Goal: Learn how to create integer variables and check their type in R.

📋 What You'll Learn

Create an integer variable with a specific value

Create a helper variable to check the type

Use a function to confirm the variable is integer

Print the result to see the type confirmation

💡 Why This Matters

🌍 Real World

Understanding integer types helps when working with data that must be whole numbers, like counts or IDs.

💼 Career

Many data analysis and programming jobs require knowing how to handle different data types correctly.

1

Create an integer variable

Create a variable called my_number and assign it the integer value 42L.

R Programming

# Create a variable called my_number and assign it the integer 42L
# Your code here

Need a hint?

Use L after the number to make it an integer in R.

2

Create a helper variable to check type

Create a variable called type_check and assign it the result of typeof(my_number).

R Programming

my_number <- 42L
# Create a variable called type_check to store typeof(my_number)
# Your code here

Need a hint?

Use the typeof() function to find the type of a variable.

3

Check if the variable is integer

Create a variable called is_integer and assign it the result of is.integer(my_number).

R Programming

my_number <- 42L
type_check <- typeof(my_number)
# Create a variable called is_integer to check if my_number is integer
# Your code here

Need a hint?

Use the is.integer() function to check if a variable is integer.

4

Print the type check and integer check results

Use print(type_check) and print(is_integer) to display the type and integer check results.

R Programming

my_number <- 42L
type_check <- typeof(my_number)
is_integer <- is.integer(my_number)
# Print type_check and is_integer
# Your code here

Need a hint?

Use two print statements to show the values of type_check and is_integer.
