R Programming: Count Number of values in a Range in a given Vector

R Programming: Vector Exercise-22 with Solution

Write a R program to count number of values in a range in a given vector.

Sample Solution :

R Programming Code :

# Create a vector 'v' with a sequence of values
v = c(0, 10, 20, 30, 40, 50, 60, 70, 80, 90)

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

# Print the original vector 'v'
print(v)

# Count the number of values in vector 'v' that are greater than 10 and less than 50
ctr = sum(v > 10 & v < 50)

# Print a message indicating the result of the count
print("Number of vector values between 10 and 50:")

# Print the count of values that are within the specified range
print(ctr)

Output:

[1] "Original vector:"
 [1]  0 10 20 30 40 50 60 70 80 90
[1] "Number of vector values between 10 and 50:"
[1] 3                         

Explanation:

• Create a vector:
• v = c(0, 10, 20, 30, 40, 50, 60, 70, 80, 90)
  A vector v is created containing a sequence of numeric values from 0 to 90.
• Print the original vector:
• print("Original vector:")
  Prints a message indicating the next output will display the original vector.
• Display the vector:
• print(v)
  Displays the elements of the vector v.
• Count values in a range:
• ctr = sum(v > 10 & v < 50)
  The code checks which elements of v are greater than 10 and less than 50. The sum() function counts how many elements meet this condition, storing the result in ctr.
• Print message (Count result):
• print("Number of vector values between 10 and 50:")
  Prints a message indicating the result of the count will follow.
• Print the count of values:
• print(ctr)
  Displays the total count of values in v that are between 10 and 50. In this case, the count is 3.
