R Data Mining

Overview of this book

R is widely used to leverage data mining techniques across many different industries, including finance, medicine, scientific research, and more. This book will empower you to produce and present impressive analyses from data, by selecting and implementing the appropriate data mining techniques in R. It will let you gain these powerful skills while immersing in a one of a kind data mining crime case, where you will be requested to help resolving a real fraud case affecting a commercial company, by the mean of both basic and advanced data mining techniques. While moving along the plot of the story you will effectively learn and practice on real data the various R packages commonly employed for this kind of tasks. You will also get the chance of apply some of the most popular and effective data mining models and algos, from the basic multiple linear regression to the most advanced Support Vector Machines. Unlike other data mining learning instruments, this book will effectively expose you the theory behind these models, their relevant assumptions and when they can be applied to the data you are facing. By the end of the book you will hold a new and powerful toolbox of instruments, exactly knowing when and how to employ each of them to solve your data mining problems and get the most out of your data. Finally, to let you maximize the exposure to the concepts described and the learning process, the book comes packed with a reproducible bundle of commented R scripts and a practical set of data mining models cheat sheets.

Develop an R markdown report in RStudio


There are three kinds of basic contents of an R markdown document:

  • Text chunks
  • Inline R code
  • Code chunks

A brief introduction to markdown 

Now that you have deleted all of the content originally provided within the template, you actually find yourself in some kind of text field where it is possible to write down characters as in a common .txt file. To be more precise though, what you are going to write here will not be interpreted as common text but rather as Markdown code. Behind this name, there is a really convenient technical solution developed by John Gruber to provide people with a way to write in plain text documents that could lately be rendered as LaTeX, .pdf, or even .html

Basically, when you write in markdown, you don't have to worry about formatting or alignment anymore, since this will be eventually handled from subsequent rendering instruments, such as the rmarkdown functions in this case. All you have to worry about is specifying the headings...
