Count the Occurrences of a specific value in a Vector in R Programming

R Programming: Vector Exercise-11 with Solution

Write a R program to count the specific 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 count of the specific value 20 in the vector
print("Count specific value(20) in above vector:")

# Count the number of occurrences of the value 20 in vector 'x' and print the result
print(sum(x == 20))

Output:

[1] "Original Vectors:"
[1] 10 20 30 20 20 25  9 26
[1] "Count specific value(20) in above vector:"
[1] 3                         

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("Count specific value(20) in above vector:"): Prints the label "Count specific value(20) in above vector:" to indicate that the following output will show the count of the value 20 in vector x.
• print(sum(x==20)): Counts the number of occurrences of the value 20 in vector x and prints the result. The sum(x==20) counts how many times the condition x==20 is TRUE.
