R Programming: Add a new item g4 = "Python" to a given list

Last update on December 21 2024 10:11:26 (UTC/GMT +8 hours)

Write a R program to add a new item g4 = "Python" to a given list.

Sample list: (g1 = 1:10, g2 = "R Programming", g3 = "HTML")

Sample Solution :

R Programming Code :

# Create a list with three items: g1, g2, and g3
list1 = list(g1 = 1:10, g2 = "R Programming", g3 = "HTML")

# Print a message indicating the original list
print("Original list:")

# Display the original list
print(list1)

# Print a message indicating a new vector will be added to the list
print("Add a new vector to the said list:")

# Add a new item 'g4' to the list, assigning it the value "Python"
list1$g4 = "Python"

# Print the updated list with the new item
print(list1)

Output:

[1] "Original list:"
$g1
 [1]  1  2  3  4  5  6  7  8  9 10

$g2
[1] "R Programming"

$g3
[1] "HTML"

[1] "Add a new vector to the said list:"
$g1
 [1]  1  2  3  4  5  6  7  8  9 10

$g2
[1] "R Programming"

$g3
[1] "HTML"

$g4
[1] "Python"
                         

Explanation:

• Creation of a List:
• list1 = list(g1 = 1:10, g2 = "R Programming", g3 = "HTML")
• A list named list1 is created with three elements:
• g1 is a vector containing numbers from 1 to 10.
• g2 is a string "R Programming".
• g3 is a string "HTML".
• Print Original List:
• print("Original list:")
• Prints the message "Original list:" to indicate the list before any modifications.
• Display Original List:
• print(list1)
• Outputs the content of list1, showing its original elements.
• Print Addition Message:
• print("Add a new vector to the said list:")
• Prints a message indicating that a new item is going to be added to the list.
• Add a New Item to the List:
• list1$g4 = "Python"
• Adds a new item g4 with the value "Python" to the list1.
• Print Updated List:
• print(list1)
• Displays the updated list1 including the newly added g4 item.
