The digital world we live in has given companies and people access to staggering amounts of data, and anyone that 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.

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

This interactive course will get you up to speed and assumes no prior knowledge of R. You'll start with the very basics and work your way up to advanced concepts like exception handling. By the time you're done, you'll be able to write detailed, useful code in R yourself.

## What are Loops?

There may be a situation when we need to execute a **block of code** multiple times. 

In general, statements are executed sequentially, which means one after another. The first statement executed first, followed by the second, and so on. However, now we want certain statements to be executed again and again given that a condition is satisfied.

### Printing Numbers Example
Suppose we are given a task to print numbers from $1$ to $5$. We can use $5$ `print()` statements for this:
