Find the Second Highest Value in a Vector using R Programming

Last update on December 21 2024 10:11:43 (UTC/GMT +8 hours)

Write a R program to find second highest value in a given vector.

Sample Solution :

R Programming Code :

 # Create a numeric vector 'x' with elements 10, 20, 30, 20, 20, 25, 9, and 26
x = c(10, 20, 30, 20, 20, 25, 9, 26)

# Print a message indicating the display of the original vector
print("Original Vectors:")

# Print the contents of vector 'x'
print(x)

# Print a message indicating the operation to find the second highest value
print("Find second highest value in a given vector:")

# Calculate the length of vector 'x'
l = length(x)

# Sort vector 'x' and print the second highest value by indexing
print(sort(x, partial = l-1)[l-1])

Output:

[1] "Original Vectors:"
[1] 10 20 30 20 20 25  9 26
[1] "Find second highest value in a given vector:"
[1] 26                         

Explanation:

• x = c(10, 20, 30, 20, 20, 25, 9, 26): Creates a numeric vector x with the elements 10, 20, 30, 20, 20, 25, 9, and 26.
• print("Original Vectors:"): Prints the label "Original Vectors:" to indicate that the following output will display the vector x.
• print(x): Prints the contents of vector x.
• print("Find second highest value in a given vector:"): Prints the label "Find second highest value in a given vector:" to indicate that the following output will show the second highest value in vector x.
• l = length(x): Calculates the length of vector x and assigns it to variable l.
• print(sort(x, partial = l-1)[l-1]):
• sort(x, partial = l-1): Sorts the vector x and ensures the element at position l-1 (second last position) is included in the sorting.
• [l-1]: Retrieves the second last element from the sorted vector, which is the second highest value.
• Prints the second highest value from vector x.
