We live in an age where data generated and collected in a fraction of a minute is enormous. To get insight out of these data they must analysed. Several tools have been developed to tacke the issue of data and obtain knowledge out of this digital data age. One of the tools is the R programming language, which has increased recently and become a one-stop solution to data problem.

In this book, I introduce to the readers some of the useful packages and tools in R that are commonly used to handle and tranform data and produce elegant graphics with R programming language. The book talks about coding using R programming languages. Coding is nothing more than telling a computer what to do in a language the computer understands. Learning to code will help you to develop critical thinking skills and ability to solve problems. We will cover various analytical processes and methods that will help reader to apply them to analyse their own datasets.
