How to Reverse a Vector in R - Step by Step Examples

How to Reverse a Vector in R ?

Answer

To reverse a vector in R, you can use the `rev()` function.


✐ Examples

1 Reverse a Vector

In this example,

  1. We create a vector named vec containing elements.
  2. We use the rev() function to reverse the order of elements in the vector.

R Program

vec <- c(1, 2, 3, 4, 5)
reversed_vec <- rev(vec)

Output

[1] 5 4 3 2 1

2 Reverse a Character Vector

In this example,

  1. We create a character vector named char_vec containing strings.
  2. We use the rev() function to reverse the order of strings in the vector.

R Program

char_vec <- c("apple", "banana", "cherry")
reversed_char_vec <- rev(char_vec)

Output

[1] "cherry" "banana" "apple"

Summary

In this tutorial, we learned How to Reverse a Vector in R language with well detailed examples.
