Riassunto:

The R language is widely used by statisticians for data analysis, and the popularity of R programming has therefore increased substantially in recent years. The emerging Internet of Things (IoT) gathers increasing amounts of data that can be analyzed to gain useful insights into trends.

R for Data Analysis in easy steps has an easy-to-follow style that will appeal to anyone who wants to produce graphic visualizations to gain insights from gathered data.

R for Data Analysis in easy steps begins by explaining core programming principles of the R programming language, which stores data in “vectors” from which simple graphs can be plotted.

Next, the book describes how to create “matrices” to store and manipulate data from which graphs can be plotted to provide better insights. This book then demonstrates how to create “data frames” from imported data sets, and how to employ the “Grammar of Graphics” to produce advanced visualizations that can best illustrate useful insights from your data.

R for Data Analysis in easy steps contains separate chapters on the major features of the R programming language. There are complete example programs that demonstrate how to create Line graphs, Bar charts, Histograms, Scatter graphs, Box plots, and more. The code for each R script is listed, together with screenshots that illustrate the actual output when that script has been executed. The free, downloadable example R code is provided for clearer understanding.

By the end of this book you will have gained a sound understanding of R programming, and be able to write your own scripts that can be executed to produce graphic visualizations for data analysis. You need have no previous knowledge of any programming language, so it's ideal for the newcomer to computer programming.

Descrizione libreria

We are a family run online bookshop based in Wales at the western edge of the Brecon Beacons National park and have been selling books online since October 2004. I have always had a love of books and it eventually got to the stage where my own book collection began to take over the family home! I reluctantly decided to sell a few of my own books on Amazon and was astonished at how quickly they sold. I was hooked and decided to start buying and selling books as a small part-time business from my spare bedroom. The business rapidly expanded, taking over the spare bedroom and my garage, swiftly followed by a spare bedroom in my mother's house and her garage! I acquired a small industrial unit in February 2007 and took the plunge to go full-time in March 2007, closely followed by my wife in September 2007. In October 2007 we moved in to larger premises and also took on our first members of staff to assist with the ever increasing workload. Our aim is to ensure that the people who buy our books enjoy the same service that we would hope for when purchasing a book ourselves. To that end, we endeavour to give all our books accurate descriptions, price them accordingly and dispatch swiftly and safely. All orders are dispatched within one working day, Monday to Friday. We will endeavour to answer all queries by email within 24 hours.
