Numeric and character vectors in R Programming - Mini Project: Build & Apply

Numeric and character vectors

📖 Scenario: You are organizing a small party and want to keep track of the number of guests and their favorite drinks.

🎯 Goal: Create numeric and character vectors in R to store the number of guests and their favorite drinks, then display the information.

📋 What You'll Learn

Create a numeric vector called guest_counts with the exact values 5, 3, 7

Create a character vector called favorite_drinks with the exact values "Tea", "Coffee", "Juice"

Create a variable called total_guests that sums all values in guest_counts

Print the total_guests value

Print the favorite_drinks vector

💡 Why This Matters

🌍 Real World

Keeping track of guest counts and preferences helps in planning events and ordering the right amount of food and drinks.

💼 Career

Data analysts and event planners often work with numeric and character data to summarize and report information clearly.

1

Create the numeric vector

Create a numeric vector called guest_counts with the exact values 5, 3, 7.

R Programming

# Create the numeric vector guest_counts with values 5, 3, 7
# Your code here

Need a hint?

Use the c() function to combine numbers into a vector.

2

Create the character vector

Create a character vector called favorite_drinks with the exact values "Tea", "Coffee", "Juice".

R Programming

guest_counts <- c(5, 3, 7)
# Create the character vector favorite_drinks with values "Tea", "Coffee", "Juice"
# Your code here

Need a hint?

Use the c() function with quotes around each drink name.

3

Calculate total guests

Create a variable called total_guests that sums all values in the guest_counts vector.

R Programming

guest_counts <- c(5, 3, 7)
favorite_drinks <- c("Tea", "Coffee", "Juice")
# Create total_guests by summing guest_counts
# Your code here

Need a hint?

Use the sum() function to add all numbers in the vector.

4

Print the results

Print the value of total_guests and then print the favorite_drinks vector.

R Programming

guest_counts <- c(5, 3, 7)
favorite_drinks <- c("Tea", "Coffee", "Juice")
total_guests <- sum(guest_counts)
# Print total_guests
# Print favorite_drinks
# Your code here

Need a hint?

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