How to access the last value in a given vector in R programming?

For writing an R program to access the last value in a given vector, we are using a built-in function tail(). The tail() function helps to return the last n rows of the dataset. The syntax of this method is like 

tail(x,n=number)

where,

  • x is the input dataset/data frame
  • n is the number of rows that the function should display.

In this R program, we are printing the original vectors and then we directly give the values to built-in functions. And print the function result. Here we used variable A for assigning vector values.

ALGORITHM

STEP 1: Assign variable A with vector values

STEP 2: First we are displaying the original vector values

STEP 3: Call the function tail as tail(A,n=1)

STEP 4: print the result of the function

 

R Source Code

                                          A= c(32, 40, 12, 23, 27, 38, 9, 17)
print("Original Vectors:")
print(A)
print("Access the last value of the vector:")
print(tail(A, n=1))

                                      

OUTPUT

[1] "Original Vectors:"
[1] 32, 40, 12, 23, 27, 38, 9, 17
[1] "Access the last value of the vector:"
[1] 17
