The high-level language of R is recognized as one of the most powerful and flexible statistical software environments, and is rapidly becoming the standard setting for quantitative analysis, statistics and graphics. R provides free access to unrivalled coverage and cutting-edge applications, enabling the user to apply numerous statistical methods ranging from simple regression to time series or multivariate analysis. Building on the success of the author’s bestselling Statistics: An Introduction using R, The R Book is packed with worked examples, providing an all inclusive guide to R, ideal for novice and more accomplished users alike. The book assumes no background in statistics or computing and introduces the advantages of the R environment, detailing its applications in a wide range of disciplines. Provides the first comprehensive reference manual for the R language, including practical guidance and full coverage of the graphics facilities. Introduces all the statistical models covered by R, beginning with simple classical tests such as chi-square and t-test. Proceeds to examine more advance methods, from regression and analysis of variance, through to generalized linear models, generalized mixed models, time series, spatial statistics, multivariate statistics and much more. The R Book is aimed at undergraduates, postgraduates and professionals in science, engineering and medicine. It is also ideal for students and professionals in statistics, economics, geography and the social sciences.

The use of wind energy to generate electricity is now well accepted with a large industry manufacturing and installing thousands of MWs of new capacity each year. Although there are exciting new developments, particularly in very large wind turbines, and many challenges remain, there is a considerable body of established knowledge concerning the science and technology of wind turbines. This book is intended to record some of this knowledge and to present it in a form suitable for use by students (at final year undergraduate or post-graduate level) and by those involved in the design, manufacture or operation of wind turbines. The overwhelming majority of wind turbines presently in use are horizontal-axis, land- SCOPE OF THE BOOK 7 based turbines connected to a large electricity network. These turbines are the subject of this book.

Spectroscopy

At the end of this useful book, the three techniques are applied to selected examples for demonstrating an integrated approach of analysis. This is a book that belongs in the hands of any organic chemist who wants to determine the structure of his molecules and intermediates under actual study. I am convinced that the volume will receive a very positive reception from chemists dealing with the syntheses of molecules or with the study of natural products. It provides the information and the recipes for the successful usage of the indispensable and marvelous tools of spectroscopy.

For thousands of years, technological innovation – the application of knowledge about tools, materials, processes, and techniques to problem solving (Afuah, 2003) – has had a profound effect on our lives as people, sometimes positively, and other times negatively, as any user of electronic mail can attest. Perhaps more importantly for the scholarly study of business, technological innovation has been a central component of the way in which new economic value is created by permitting people and companies to use existing resources more efficiently, as well as to come up with products and services that meet people’s needs in ways that were not met before (Mokyr, 1990). Because technological innovation creates economic value, it also affects the growth and decline in shareholder wealth. This effect on shareholder wealth impacts all shareholders, regardless of whether they are founding entrepreneurs, employees, or investors in companies, and regardless of whether they are shareholders in the innovating company or the company that competes with innovators.
