Statistical Analysis with R

The digital world we live in has given companies and people access to staggering amounts of data, and anyone who can make use of that to drive valuable insights stands to benefit. The ability to work with large amounts of data is becoming a standard requirement for countless jobs across multiple industries.

R, probably the most well-known language for data analysis, has been used for years due to its robust statistical functionality, outstanding graphing ability, and extensibility through packages.

This interactive module will get us up to speed with R and assumes no prior knowledge of it. We'll start with the very basics and work our way up to advanced concepts like exception handling. By the time we're done, we'll be able to write detailed, useful code in R.

# Syntax of a `repeat` loop

The syntax for `repeat` loop in R language:

```r
repeat 
{
  statement
}
```
> In the statement block, we must use the `break` statement to exit the loop.

The `repeat` loop runs as long as it is not broken explicitly. 

myNumber <- 1

repeat
{
  print(myNumber)
  myNumber = myNumber + 1

  if(myNumber > 10)
    break
}

Here, the `break` statement is executed when the conditional statement `myNumber > 10` evaluates to `TRUE`. 

> **Note:** The **conditional statement** we are using in this loop is opposite to that we used for the `while` loop. This is because the `while` loop can be interpreted as _loop until the condition returns_ `FALSE`. 

However, the `repeat` loop can be interpreted as _keep looping_, and if the **breaking condition** returns `TRUE`, only then, break the loop. 

`Break` statement can be used with other loops as well to explicitly break them. For example, we can modify the original `while` loop that used to print numbers from $1$ to $10$ to print until $5$ using `break` statement.

We will be learning all about the repeat statement in this lesson.
