The Book of R is a comprehensive, beginner-friendly guide to R, the world’s most popular programming language for statistical analysis. Even if you have no programming experience and little more than a grounding in the basics of mathematics, you’ll find everything you need to begin using R effectively for statistical analysis. You’ll start with the basics, like how to handle data and write simple programs, before moving on to more advanced topics, like producing statistical summaries of your data and performing statistical tests and modeling. You’ll even learn how to create impressive data visualizations with R’s basic graphics tools and contributed packages, like ggplot2 and ggvis, as well as interactive 3D visualizations using the rgl package. Dozens of hands-on exercises (with downloadable solutions) take you from theory to practice, as you learn: –The fundamentals of programming in R, including how to write data frames, create functions, and use variables, statements, and loops –Statistical concepts like exploratory data analysis, probabilities, hypothesis tests, and regression modeling, and how to execute them in R –How to access R’s thousands of functions, libraries, and data sets –How to draw valid and useful conclusions from your data –How to create publication-quality graphics of your results Combining detailed explanations with real-world examples and exercises, this book will provide you with a solid understanding of both statistics and the depth of R’s functionality. Make The Book of R your doorway into the growing world of data analysis.

During the Vietnam War, the U.S. Army deployed electronic sensors along the Ho Chi Minh Trail in Laos, Cambodia, North Vietnam, and South Vietnam in order to detect and track troop and vehicle movements. At approximately 8,100 miles in length, monitoring this sophisticated logistics network_consisting of roads, trails, vehicle parks, petroleum pipelines, and storage areas_was no mean task. Since the work was classified as 'Secret' until only recently, a comprehensive story of the electronic sensors used in Southeast Asia has never been completely told. Wiring Vietnam: The Electronic Wall relates the history of the electronic detection system that was deployed during the Vietnam War. Author Anthony Tambini covers everything from the sensors used to detect seismic signals from nearby troop and vehicle movements to audio sensors that were deployed to pick up conversations of troops as well as traffic noise of vehicles to engine ignition detectors. Beginning with the conception, development, and implementation of these sensors, Tambini then relates how, ultimately, the various signals the sensors collected were transmitted to orbiting aircraft that would process and retransmit the signals onward to a base in Thailand. There the data underwent further analysis for possible targets that could be attacked from the air. Anthony Tambini, a member of the 25th Tactical Fighter Squadron based at Ubon, Thailand in the late 1960s, was part of an organization that dropped these sensors. His firsthand perspective, along with rarely seen photographs of the actual sensors used, will provide those interested in the Vietnam War and modern warfare with a clear picture of an undocumented side of history.
