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

R Source Code

B = c(14, 78, 25, 45, 95, 34, 52, 61)

print("Original Vectors:")
## [1] "Original Vectors:"
print(B)
## [1] 14 78 25 45 95 34 52 61
print("Access the last value of the vector:")
## [1] "Access the last value of the vector:"
print(tail(B, n = 1))
## [1] 61
