R Programming: Extract all elements except the third element

Last update on June 05 2025 12:57:57 (UTC/GMT +8 hours)

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.

Go to:

PREV : Write a R program to Add 10 to each element of the first vector in a given list.
NEXT : Write a R program to add a new item g4 = "Python" to a given list.
