Access the Last Value in a Vector Using R Programming

R Programming: Vector Exercise-12 with Solution

Write a R program to access the last 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 access of the last value in the vector
print("Access the last value of the said vector:")

# Access and print the last value of vector 'x' using the tail function
print(tail(x, n=1))

Output:

[1] "Original Vectors:"
[1] 10 20 30 20 20 25  9 26
[1] "Access the last value of the said 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("Access the last value of the said vector:"): Prints the label "Access the last value of the said vector:" to indicate that the following output will show the last value of vector x.
• print(tail(x, n=1)): Uses the tail function to access and print the last value of vector x. The argument n=1 specifies that only the last element should be returned.
