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

    

    In Glasgow, in the 1980s neither the Police nor the Public could understand why grown men were fighting over the rights to sell ice cream, the violence was extreme, and the streets of the housing estates were turned into war zones. Crowds of youths gathered on the street corners, while adults hung from their flat windows watching real-life scenes far more exciting than anything they could see on TV the smashing of Ice cream vans and cars, slashings and stabbings of rival Ice cream men were a nightly occurrence. And the reason behind the violence was that you could earn more money selling Ice cream than you could from selling drugs. The lack of shops in the vast run-down housing estates with thousands of families who had money to spend was a captured market providing an excellent living for the Italian families who controlled the Ice cream trade in Glasgow. Tam McGraw was building a reputation as an up and coming gangster who led a team that specialised in post office, factory, and cash and carry raids throughout Scotland. Tam McGraw realised that he could earn a lot more money a much easier way than robbing post offices, he could sell Ice cream. But first Tam had to test the strength of the Italians and the reaction of the police. McGraw went for the jugular right from the start. He knew Marchetti would not give in easily, and they would try to defend their territory. So he started with Carntyne one of Marchetti's most lucrative routes. Marchetti Brothers were about to suffer brutality and destruction of a kind they could never have imagined in their wildest nightmares. McGraw planned to be the Ice Cream King of Scotland, and Carntyne is where he would lay the foundations of his throne. Nothing or no one would stand in his way. This is the real story of the Glasgow Ice Cream Van Wars. The shocking violence mixed with a decent portion of Glaswegian humour will keep you turning the pages until the end. Written in a broad Glaswegian dialect with a lot of swearing, the author writes as he speaks. This book might not be suitable for those who prefer perfect grammar and proper English. But if you can see past that then I am sure you will find it an enjoyable read. Teddy Rennoc.

    With this practical book, you'll explore text-mining techniques with tidytext, a package that authors Julia Silge and David Robinson developed using the tidy principles behind R packages like ggraph and dplyr. You'll learn how tidytext and other tidy tools in R can make text analysis easier and more effective.The authors demonstrate how treating text as data frames enables you to manipulate, summarize, and visualize characteristics of text. You'll also learn how to integrate natural language processing (NLP) into effective workflows. Practical code examples and data explorations will help you generate real insights from literature, news, and social media.Learn how to apply the tidy text format to NLPUse sentiment analysis to mine the emotional content of textIdentify a document's most important terms with frequency measurementsExplore relationships and connections between words with the ggraph and widyr packagesConvert back and forth between R's tidy and non-tidy text formatsUse topic modeling to classify document collections into natural groupsExamine case studies that compare Twitter archives, dig into NASA metadata, and analyze thousands of Usenet messages

     Yet Foreman is both unelected and unpopular. Some say he and his cronies are almost communist – Russian sympathisers, perhaps? Almost everybody around him believes him to be a repellent human being and fundamentally unfit for office. But can Foreman be stopped and should he be stopped? In the aftermath of the Vietnam War, few Americans have an appetite for conflict, but there is an exception: The Destruction Committee. Forged in the theatre of war, the Destruction Committee comprises top-grade soldiers, men who know how to kill quickly, efficiently, ruthlessly and without being caught. Operating well outside the law, the Destruction Committee nonetheless declares itself dedicated to the greater good and minimal damage. When it comes to those it deems a threat to society, however, The Destruction Committee kills without mercy. And The Destruction Committee believes that Carlyn Foreman is a threat. The Destruction Committee is a classic thriller that touches upon the nature of American politics, the psychological effects of war and death, and the allocation of political power.
