6. Installing R and R Studio (Mac, Linux & Windows)

DOWNLOADING AND INSTALLING THE REQUIRED R PACKAGES

Go to the R website to download the latest R package
Download the desired R distribution for your OS, for my setup it is Windows.
Once you are directed to the download page, press install R for the first time, and click on the download link.
You just need to download and install the R distribution on your machine.
For mac version, its the same. Just download the latest R binary distribution on the top of the page.
Just install the R distribution using the default configuration.
But you also need an IDE to work with your programming language of R.
Most people find the best and most convenient IDE to use, is RStudio.

Open RStudio and you should see the UI displayed on your screen.
Go to tools and Global Options on a Windows machine.
On Mac, it will be somewhere in the top left and it will be preferences.
You can change your preference under Appearance, for different schemes, styles and font size
If you want to have default, just select TextMate(Default) and apply.
Typing your first command in R, in RStudio IDE.
```
  print("Hello World!")
```
Just press Ctrl Enter after the line to run the code.
