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.

## What is a Function?

A function is a set of **statements**  that are executed together to achieve a specific goal or task.

You might remember that **everything in R is an object**. From this, we can conclude that a function is also an object in R language.

## Syntax of a Function
An R function is created by using the keyword `function`. The basic syntax is as follows:

```r
functionName <- function(argument1, argument2, ..., argumentN) 
{
   # Statements 
}
```
Let's have a look at the illustration:
