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.

## Recursive Functions

We can also call the function itself from its body. Such a function is called a **recursive function**. A **recursive function** is a function that calls itself during its _execution_. 

Recursion enables the function to repeat itself several times, collecting the result at the end of each iteration. 

### Components of a Recursive Function
Each recursive function has two parts:

* **Base Case:** The base case is where the call to the function stops, i.e., it does not make any subsequent recursive calls.

* **Recursive Case:** The recursive case is where the function calls itself again and again until it reaches the base case.

Let's have a look at an example. Here, we print numbers from $10$ to $1$ using recursion. We call the function `printNumbers()` inside itself.
