Find elements of a Vector not in another Vector in R

Last update on December 21 2024 10:11:46 (UTC/GMT +8 hours)

Write a R program to find the elements of a given vector that are not in another given vector.

Sample Solution :

R Programming Code :

# Define the first vector
a = c(0, 10, 10, 10, 20, 30, 40, 40, 40, 50, 60)

# Define the second vector
b = c(10, 10, 20, 30, 40, 40, 50)

# Print the first vector
print("Original vector-1:")
print(a)

# Print the second vector
print("Original vector-2:")
print(b)

# Find elements in the first vector that are not in the second vector
print("Elements of a that are not in b:")
result = setdiff(a, b)

# Print the result
print(result)

Output:

[1] "Original vector-1:"
 [1]  0 10 10 10 20 30 40 40 40 50 60
[1] "Original vector-2:"
[1] 10 10 20 30 40 40 50
[1] "Elements of a that are not in b:"
[1]  0 60                         

Explanation:

• The code starts by defining two vectors a and b with specific elements. Vector a includes elements such as 0, 10, 20, 30, 40, 50, and 60, while vector b includes elements like 10, 20, 30, 40, and 50.
• It then prints "Original vector-1:" followed by the elements of vector a.
• Similarly, it prints "Original vector-2:" followed by the elements of vector b.
• The code proceeds to find the elements in vector a that are not present in vector b using the setdiff() function.
• Finally, it prints "Elements of a that are not in b:" followed by the result, which shows the unique elements in a that do not appear in b.
