R Programming: Extract all elements except the third element

R Programming: List Exercise-17 with Solution

Write a R program to extract all elements except the third element of the first vector of a given list.

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

Sample Solution :

R Programming Code :

# Create a list with three elements: a numeric vector, and two strings
list1 = list(g1 = 1:10, g2 = "R Programming", g3 = "HTML")

# Print the original list
print("Original list:")
print(list1)

# Print the first vector (g1) from the list
print("First vector:")
print(list1$g1)

# Remove the third element from the first vector (g1)
print("First vector without third element:")
list1$g1 = list1$g1[-3]

# Print the modified first vector without the third element
print(list1$g1)

Output:

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

$g2
[1] "R Programming"

$g3
[1] "HTML"

[1] "First vector:"
 [1]  1  2  3  4  5  6  7  8  9 10
[1] "First vector without third element:"
[1]  1  2  4  5  6  7  8  9 10                         

Explanation:

• Create a list (list1):
• The list list1 contains three elements:
• g1: A numeric vector from 1 to 10.
• g2: A string "R Programming".
• g3: A string "HTML".
• Print the original list:
• The entire list list1 is printed, showing all elements (the vector and the two strings).
• Print the first vector (g1):
• The first element of the list, which is the numeric vector g1, is printed.
• Remove the third element of the first vector:
• The third element of the vector g1 is removed using list1$g1[-3].
• Print the modified first vector:
• The updated vector, which no longer contains the third element, is printed.
