💼 Career

Knowing how to create and manage lists is a basic skill for data handling and programming in many jobs.

1

Create the guest list

Create a list called guests with these exact names: "Alice", "Bob", and "Charlie".

R Programming

# Create the list called guests with the names
# Your code here

Need a hint?

Use the list() function to create a list with the names inside.

2

Add a new guest

Create a variable called new_guest and set it to the string "Diana".

R Programming

guests <- list("Alice", "Bob", "Charlie")
# Create a variable new_guest with the value "Diana"
# Your code here

Need a hint?

Use the assignment operator <- to set new_guest to "Diana".

3

Add the new guest to the list

Add the new_guest to the end of the guests list using the append() function and update guests with the result.

R Programming

guests <- list("Alice", "Bob", "Charlie")
new_guest <- "Diana"
# Append new_guest to guests and update guests
# Your code here

Need a hint?

Use append(guests, new_guest) to add the new guest to the list.

4

Display the guest list

Print the guests list to show all guest names.

R Programming

guests <- list("Alice", "Bob", "Charlie")
new_guest <- "Diana"
guests <- append(guests, new_guest)
# Print the guests list
# Your code here

Need a hint?

Use the print() function to display the list.
