R Program to access the last value in a given vector

How to access the last value in a given vector

Here we are explaining how to write an R program to access the last value in a given vector. Here we are using a built-in function tail() for this finding. The tail() function helps to returns the last n rows of the dataset.The syntax of this method is like 

tail(x,n=number) #where x is the input dataset/dataframe and n is the number of rows that the function should display.
 

How to access the last value in a given vector in R program

Below are the steps used in the R program to get the last value in a given vector. In this R program, 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 print 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
