Garrett Grolemund,Hadley Wickham,: R for Data Science : Import, Tidy, Transform, Visualize, and Model Data
What exactly is data science? With this book, you'll gain a clear understanding of this discipline for discovering natural laws in the structure of data. Along the way, you'll learn how to use the versatile R programming language for data analysis.Whenever you measure the same thing twice, you get two results--as long as you measure precisely enough. This phenomenon creates uncertainty and opportunity. Author Garrett Grolemund, Master Instructor at RStudio, shows you how data science can help you work with the uncertainty and capture the opportunities. You'll learn about: Data Wrangling--how to manipulate datasets to reveal new informationData Visualization--how to create graphs and other visualizationsExploratory Data Analysis--how to find evidence of relationships in your measurementsModelling--how to derive insights and predictions from your dataInference--how to avoid being fooled by data analyses that cannot provide foolproof resultsThrough the course of the book, you'll also learn about the statistical worldview, a way of seeing the world that permits understanding in the face of uncertainty, and simplicity in the face of complexity.
- Getting my financial disasters out of the way early--before I was married or had a family--so that the only credit score that I wrecked was my own. In this vivid account of the U.S. Army's legendary 10th Mountain Division's heroic stand in the mountains of Afghanistan, Captain Sean Parnell shares an action-packed and highly emotional true story of triumph, tragedy, and the extraordinary bonds forged in battle. At twenty-four years of age, U.S. Army Ranger Sean Parnell was named commander of a forty-man elite infantry platoon-a unit that came to be known as the Outlaws-and was tasked with rooting out Pakistan-based insurgents from a mountain valley along Afghanistan's eastern frontier. Parnell and his men assumed they would be facing a ragtag bunch of civilians, but in May 2006 what started out as a routine patrol through the lower mountains of the Hindu Kush became a R for Data Science : Import, Tidy, Transform, Visualize, and Model Data download epub brutal ambush. Barely surviving the attack, Parnell's men now realized that they faced the most professional and seasoned force of light infantry the U.S. Army had encountered since the end of World War II. What followed was sixteen months of close combat, over the course of which the platoon became Parnell's family.
