This book introduces you to R, RStudio, and the tidyverse, a collection of R packages designed to work together to make data science fast, fluent, and fun. Suitable for readers with no previous programming experience, R for Data Science is designed to get you doing data science as quickly as possible. Authors Hadley Wickham and Garrett Grolemund guide you through the steps of importing, wrangling, exploring, and modeling your data and communicating the results. You'll get a complete, big-picture understanding of the data science cycle, along with basic tools you need to manage the details. Each section of the book is paired with exercises to help you practice what you've learned along the way. You'll learn how to: Wrangle—transform your datasets into a form convenient for analysis Program—learn powerful R tools for solving data problems with greater clarity and ease Explore—examine your data, generate hypotheses, and quickly test them Model—provide a low-dimensional summary that captures true "signals" in your dataset Communicate—learn R Markdown for integrating prose, code, and results

Book Description
Turn your R code into packages that others can easily download and use. This practical book shows you how to bundle reusable R functions, sample data, and documentation together by applying author Hadley Wickham’s package development philosophy. In the process, you’ll work with devtools, roxygen, and testthat, a set of R packages that automate common development tasks. Devtools encapsulates best practices that Hadley has learned from years of working with this programming language. Ideal for developers, data scientists, and programmers with various backgrounds, this book starts you with the basics and shows you how to improve your package writing over time. You’ll learn to focus on what you want your package to do, rather than think about package structure. Learn about the most useful components of an R package, including vignettes and unit tests Automate anything you can, taking advantage of the years of development experience embodied in devtools Get tips on good style, such as organizing functions into files Streamline your development process with devtools Learn the best way to submit your package to the Comprehensive R Archive Network (CRAN) Learn from a well-respected member of the R community who created 30 R packages, including ggplot2, dplyr, and tidyr

Book Description
Can a lost girl save a found dog? Find out in this unforgettable story about discovering true friendship, finding home, and the possibilities of forgiveness. Hadley is angry about a lot of things: Her mom going to jail. Having to move to another state to live with her older sister, Beth, even though they haven't spoken in five years. Leaving her friends and her school behind. And going blind. But then Hadley meets Lila. Lila is an abandoned dog who spends her days just quietly lying around at the local dog rescue where Beth works. She doesn't listen to directions or play with the other dogs or show any interest in people. So when Lila comes and sits by Hadley (which is hardly anything, but it's more than she's done with others), Beth thinks maybe Hadley can help Lila. She tells Hadley they'll bring Lila home as a foster dog and Hadley can teach her to follow commands, walk on a leash, and be more of a people dog so she's ready to be adopted. Only working with Lila is harder than Hadley thought, and so is the mobility training she starts taking to help with her failing vision. It feels like Lila is too stubborn to train and that learning to use a cane is impossible. But unless Hadley can help Lila, she'll never be adopted into a home. If Hadley could just let go of her anger, she might be able to save Lila ... and herself. New York Times bestselling author Kody Keplinger weaves an unforgettable story about discovering true friendship, finding home, and the possibilities of forgiveness.

Book Description
Winner of the Edge Hill Short Story Prize A New York Times Notable Book of the Year An NPR Best Book of the Year The award-winning author of The Past once again "crystallizes the atmosphere of ordinary life in prose somehow miraculous and natural" (Washington Post), in a collection of stories that elevate the mundane into the exceptional. The author of six critically acclaimed novels, Tessa Hadley has proven herself to be the champion of revealing the hidden depths in the deceptively simple. In these short stories it’s the ordinary things that turn out to be most extraordinary: the history of a length of fabric or a forgotten jacket. Two sisters quarrel over an inheritance and a new baby; a child awake in the night explores the familiar rooms of her home, made strange by the darkness; a housekeeper caring for a helpless old man uncovers secrets from his past. The first steps into a turning point and a new life are made so easily and carelessly: each of these stories illuminate crucial moments of transition, often imperceptible to the protagonists. A girl accepts a lift in a car with some older boys; a young woman reads the diaries she discovers while housesitting. Small acts have large consequences, some that can reverberate across decades; private fantasies can affect other people, for better and worse. The real things that happen to people, the accidents that befall them, are every bit as mysterious as their longings and their dreams. Bad Dreams and Other Stories demonstrates yet again that Tessa Hadley "puts on paper a consciousness so visceral, so fully realized, it heightens and expands your own. She is a true master" (Lily King, author of Euphoria).

Book Description
Published posthumously in 1964, A Moveable Feast remains one of Ernest Hemingway's most beloved works. Since Hemingway's personal papers were released in 1979, scholars have examined and debated the changes made to the text before publication. Now this new special restored edition presents the original manuscript as the author prepared it to be published. Featuring a personal foreword by Patrick Hemingway, Ernest's sole surviving son, and an introduction by the editor and grandson of the author, Seán Hemingway, this new edition also includes a number of unfinished, never-before-published Paris sketches revealing experiences that Hemingway had with his son Jack and his first wife, Hadley. Also included are irreverent portraits of other luminaries, such as F. Scott Fitzgerald and Ford Madox Ford, and insightful recollections of his own early experiments with his craft. Sure to excite critics and readers alike, the restored edition of A Moveable Feast brilliantly evokes the exuberant mood of Paris after World War I and the unbridled creativity and unquenchable enthusiasm that Hemingway himself epitomized.

Book Description
"The Cavendishes flourished during the high tide of British aristocracy following the revolution of 1688-89, and the case can be made that this aristocracy knew its finest hour when Henry Cavendish gently laid his delicate weights in the pan of his incomparable precision balance. For this it took two generations and two kinds of invention, one in social forms and the other in scientific technique. This biography tells how it came to pass."--BOOK JACKET.
