This book presents an easy way to learn how to perform an analytical task in R, without having to navigate through its extensive, idiosyncratic, and sometimes unwieldy software documentation and vast number of add-on packages. Showing how to efficiently use the powerful R system, the authors cover data management, descriptive summaries, inferential procedures, regression analysis, multivariate methods, and the creation of graphics. The text includes convenient indices organized by topic and R syntax and contains many example analyses. Data sets and code are available for download on the book’s website.
