In Detail
Machine learning, at its core, is concerned with transforming data into actionable knowledge. This fact makes machine learning well-suited to the present-day era of "big data" and "data science". Given the growing prominence of R—a cross-platform, zero-cost statistical programming environment—there has never been a better time to start applying machine learning. Whether you are new to data science or a veteran, machine learning with R offers a powerful set of methods for quickly and easily gaining insight from your data.
"Machine Learning with R" is a practical tutorial that uses hands-on examples to step through real-world application of machine learning. Without shying away from the technical details, we will explore Machine Learning with R using clear and practical examples. Well-suited to machine learning beginners or those with experience. Explore R to find the answer to all of your questions.
How can we use machine learning to transform data into action? Using practical examples, we will explore how to prepare data for analysis, choose a machine learning method, and measure the success of the process.
We will learn how to apply machine learning methods to a variety of common tasks including classification, prediction, forecasting, market basket analysis, and clustering. By applying the most effective machine learning methods to real-world problems, you will gain hands-on experience that will transform the way you think about data.
"Machine Learning with R" will provide you with the analytical tools you need to quickly gain insight from complex data.

From reader reviews:
Eunice Bosse:
Book is actually written, printed, or created for everything. You can understand everything you want by a publication. Book has a different type. As you may know that book is important matter to bring us around the world. Alongside that you can your reading ability was fluently. A publication Machine Learning with R will make you to possibly be smarter. You can feel considerably more confidence if you can know about almost everything. But some of you think in which open or reading a book make you bored. It is far from make you fun. Why they may be thought like that? Have you in search of best book or ideal book with you?
Lucile Brown:

How a lot more to be smart in obtaining any information nowadays? Of course the correct answer is reading a book. Reading a book can help persons out of this uncertainty Information mainly this Machine Learning with R book since this book offers you rich details and knowledge. Of course the data in this book hundred per cent guarantees there is no doubt in it everbody knows.
Christine Brooks:
Reading can called head hangout, why? Because if you are reading a book specially book entitled Machine Learning with R your thoughts will drift away trough every dimension, wandering in each and every aspect that maybe not known for but surely will become your mind friends. Imaging each word written in a guide then become one contact form conclusion and explanation that maybe you never get just before. The Machine Learning with R giving you another experience more than blown away the mind but also giving you useful data for your better life in this era. So now let us show you the relaxing pattern here is your body and mind is going to be pleased when you are finished reading it, like winning a casino game. Do you want to try this extraordinary paying spare time activity?
