# What is a repeat loop in R?

This recipe explains what is a repeat loop in R

1

## Recipe Objective

Loops are an important feature in R-language. It helps us to iterate through vectors, lists and process required functions to its elements. They help us to implement complex logic which requires a repetitive step. There are three different loops in R:

1. For loops
2. While loops
3. Repeat loops

Each of these loops has its own use cases. We will focus on repeat loops in this recipe by demonstrating an example

Repeat loops are used when a block of code until a stop condition or break is met. It is an alternative to do-while in traditional programming languages.

Syntax:

repeat{ // Block of code that needs to be executed until the if condition speficied is met if (boolean_condition){ break } }

## Example: To print the cubes of all the numbers starting from 2 to 6

# Creating an iterator a = 2 ​ # Using repeat loop repeat{ print(a^3) #increasing the iterator by one a=a+1 if(a<=7){ } } while(a<=6){ print(a^3) a=a+1 }
