Find the Second Highest Value in a Vector using R Programming
R Programming: Vector Exercise-13 with Solution
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.
