Then, when you knit, your computer will take the information from this yaml and will just execute your orders. We will come back on that later, but the main difference with a Word document is its structure and in particular the top part of a document that we call “yaml.” Think about the yaml as the palce where you tell your computer how you want your document to be organized: what is the title, who is the author, what is the abstract, what is the output format (pdf, ppt), etc. In order to do so, you will have to click on the “knit” button. think that to “see” your final document, you will need to “compile” it. To really grasp what is happening, you need to get your hands dirty and go through the following steps. It thus goes get the latest data available at the time you work on your document.

Every time you work on your document, the code runs as if it was the first time. It is indeed being able to leverage a great deal of computing power in something as easy to manipulate as Word. Even more than that, it is a super computer integrated in Word. It is like having Excel embedded in Word, all in the same place. Here, in the same interface you will be able to write text as you would do in Microsoft Word while being able to integrate some powerful commands in the same Word-style document. Think about RStudio as Microsoft Office, the whole suite. Now that you have created your account on RStudio.cloud, let’s begin with the environment. familiarize with the RStudio Integrated Development Environment.Throughout the chapters, useful tips will be either displayed in bold or in italics.Īt the end of the chapter, you should be able to:

You will learn a few syntax tips regarding Markdown and how to save your projects online (Git). In order to do so, RStudio, with documents written in Markdown, will be your main portal for doing your projects. In this regard, we promote reproducible research as our research method. The goal of this book is to harness the power of data science tools for business. All research projects presented here are made with RStudio, using the R programming language as well as Markdown. The various examples will often be based on my research and the various datasets I have collected through time.

Our aim here is to make students understand the concept and process of a data pipeline, from entering data into a data frame (something that looks like a Microsoft Excel sheet) to organizing and visualizing the data on a graph or in a series of graphs organized in a business dashboard. It will make you click and enter commands in your RStudio session to experience first-hand the process. I really believe they are among the players that truly help new generations to participate and take ownership of this industrial revolution 4.0. Even if you are a true bash guy, the more you use RStudio, the more you realize how helpful it is too lower the barriers to entry to the programming world and power. You could do it with Markdown and Python or Markdown and Julia likewise. From there, you can write a business analyst report (that is the goal here) with Markdown and R. So what is so great about RStudio? Well, they manged to put in one place, in a very fluid and integrated way, various languages such as R, Python and Markdown (to cite just a few). An IDE is nothing more than a graphical interface that connects a mouse click to a bash command or something not too far from that. What is it so unique about RStudio? Well, it is “just” another IDE (Integrated Development Environment). In this first chapter, you will familiarize yourself with the environment used in this book: RStudio.

It is an open source programming language and software environment for statistical computing and graphics. R is open sourceĬompared with S, R is open source. It is currently developed by the R Development Core Team. R is named partly after the first names of the first two R authors and partly as a play on the name of S. It was created by Ross Ihaka and Robert Gentleman at the University of Auckland, New Zealand. R is an implementation of the S programming language (Bell Labs).
