How to get Last Item in a Vector in R - Step by Step Examples

How to get Last Item in a Vector in R ?

To get the last item in a vector in R, you can use indexing with the length function to determine the position of the last element.

In this example,

First, we create a numeric vector named vec with a series of numeric values.
We then use the length function to determine the total number of elements in the vector vec.
The length function returns an integer value representing the number of elements in the vector.
Next, we use this length value to index the last element of the vector. In R, you can access the last element of a vector by using vec[length(vec)].
Finally, we print the last item to the console using the print function.

vec <- c(10, 20, 30, 40, 50)
last_item <- vec[length(vec)]
print(last_item)

[1] 50

In this example,

First, we create a character vector named char_vec with a series of string values.
We then use the length function to determine the total number of elements in the vector char_vec.
The length function returns an integer value representing the number of elements in the vector.
Next, we use this length value to index the last element of the vector. In R, you can access the last element of a vector by using char_vec[length(char_vec)].
Finally, we print the last item to the console using the print function.

char_vec <- c("apple", "banana", "cherry", "date", "elderberry")
last_item <- char_vec[length(char_vec)]
print(last_item)

[1] "elderberry"
