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 Wickhams package development philosophy. In the process, youll 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. Youll 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 testsAutomate anything you can, taking advantage of the years of development experience embodied in devtoolsGet tips on good style, such as organizing functions into filesStreamline your development process with devtoolsLearn 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

Create useful and usable map apps that your users will love.Turn your next map app project into a success with Designing Map Interfaces: Patterns for Building Effective Map Apps. Whether you're configuring an out-of-the-box solution, building an app using one of the readily available app builder tools, or working on a custom app project, this book will guide you toward developing more useful and usable apps. Current courses for application development focus on technology and architecture rather than the tenets of interface design. This book teaches GIS professionals, developers, and designers the principles and best practices that will help them create stunning consumer-grade apps.Designing Map Interfaces provides a language for planning and building map apps. The elements of this language are made up of user interface (UI) patterns. Each pattern describes a solution to an observed and recurring problem in UI design. This book explains when to use the pattern, why it is important, and what to consider-and in turn will help readers make educated decisions on what, why, when, and how to solve problems to make their apps work. Throughout the book, patterns are illustrated through real-world examples.Key topics include:getting started with design,selecting the right layout,interacting with the map, dealing with complex data,designing for mobile devices,building single-purpose apps, andcommon mistakes and how to avoid them.This book is aimed at anyone who configures (solution engineers, GIS professionals) or builds (developer community, designers) map apps, especially the fast-growing group of users who employ application builders and tools that create apps to publish their own data and maps on the web. Designing Map Interfaces fills the gap that documentation lacks-practical tips on how to assemble a meaningful UI.This book is the essential guide to designing map interfaces that are usable and efficient, and that look good in the process.

The need for precise, actionable, real-time Business Intelligence (BI) lies at the heart of the role of Big Data in modern commerce. In turn, the art of "Data Science" lies at the nexus of Big Data and BI, providing the essential methods by which BI can be extracted from Big Data's great black mass of constantly flowing, unstructured information. This combination has a created a new profession: an elite and specialized class of highly-compensated professionals specially skilled at data cleaning, analysis, and visualization. We call them Data Scientists, and their evolving role in the organization is one about which managers must have a clear understanding. As shown in WHAT EVERY MANAGER SHOULD KNOW ABOUT BIG DATA AND DATA SCIENCE, integrating data scientists (and the general practice of Data Science) with the organization is often a delicate process involving the redefinition of traditional roles within the enterprise as well as dealing with issues of territoriality amongst peers. To accomplish this task, managers need a firm knowledge of the what and whys of Data Science, the specific BI needs it is uniquely positioned to service, and the processes by which it functions. Such is the knowledge this important book provides.

This book contains a three step approach to help business professionals create effective presentation visuals. Step 1 is writing a headline that summarizes the message you want the audience to understand and remember from that slide. Step 2 is to select and create an effective visual for the slide. The book focuses on this step because corporate presenters have said they need the most help with this area. The different messages in business presentations are broken down into six categories. The 66 visuals shown are organized into 30 groups and sub-groups under the six categories. Each visual is explained, examples are shown, and tips for creating the visual are given. Step 3 is to focus the audience during the delivery of the slide by using callouts, building the slide piece by piece, and by organizing complex information.

Shapes are complex objects to apprehend, as mathematical entities, in terms that also are suitable for computerized analysis and interpretation. This volume provides the background that is required for this purpose, including different approaches that can be used to model shapes, and algorithms that are available to analyze them. It explores, in particular, the interesting connections between shapes and the objects that naturally act on them, diffeomorphisms. The book is, as far as possible, self-contained, with an appendix that describes a series of classical topics in mathematics (Hilbert spaces, differential equations, Riemannian manifolds) and sections that represent the state of the art in the analysis of shapes and their deformations. A direct application of what is presented in the book is a branch of the computerized analysis of medical images, called computational anatomy.

Creativity plays an important role in all human activities, from the visual arts to cinema and theatre, and in particular in science and mathematics .This volume, published only in English in the series "Mathematics and Culture", stresses the strong links between mathematics, culture and creativity in architecture, contemporary art, geometry, computer graphics, literature, theatre and cinema. So this book is designed not only for mathematicians but for all the people who have an interest in the various aspects of culture, both scientific and literary, with a special emphasis on the visual aspects.
