This richly illustrated book describes the use of interactive and dynamic graphics as part of multidimensional data analysis. Chapter topics include clustering, supervised classification, and working with missing values. A variety of plots and interaction methods are used in each analysis, often starting with brushing linked low-dimensional views and working up to manual manipulation of tours of several variables. The book is augmented by a wealth of online material.
This book introduces readers to the fundamentals of creating presentation graphics using R, based on 100 detailed and complete scripts. It shows how bar and column charts, population pyramids, Lorenz curves, box plots, scatter plots, time series, radial polygons, Gantt charts, heat maps, bump charts, mosaic and balloon charts, and a series of different thematic map types can be created using R´s Base Graphics System. Every example uses real data and includes step-by-step explanations of the figures and their programming. The open source software R is an established standard and a powerful tool for various visualizing applications, integrating nearly all technologies relevant for data visualization. The basic software, enhanced by more than 7000 extension packs currently freely available, is intensively used by organizations including Google, Facebook and the CIA. The book serves as a comprehensive reference guide to a broad variety of applications in various fields. This book is intended for all kinds of R users, ranging from experts, for whom especially the example codes are particularly useful, to beginners, who will find the finished graphics most helpful in learning what R can actually deliver.
This new edition to the classic book by ggplot2 creator Hadley Wickham highlights compatibility with knitr and RStudio. ggplot2 is a data visualization package for R that helps users create data graphics, including those that are multi-layered, with ease. With ggplot2, it´s easy to: produce handsome, publication-quality plots with automatic legends created from the plot specification superimpose multiple layers (points, lines, maps, tiles, box plots) from different data sources with automatically adjusted common scales add customizable smoothers that use powerful modeling capabilities of R, such as loess, linear models, generalized additive models, and robust regression save any ggplot2 plot (or part thereof) for later modification or reuse create custom themes that capture in-house or journal style requirements and that can easily be applied to multiple plots approach a graph from a visual perspective, thinking about how each component of the data is represented on the final plot This book will be useful to everyone who has struggled with displaying data in an informative and attractive way. Some basic knowledge of R is necessary (e.g., importing data into R). ggplot2 is a mini-language specifically tailored for producing graphics, and you´ll learn everything you need in the book. After reading this book you´ll be able to produce graphics customized precisely for your problems, and you´ll find it easy to get graphics out of your head and on to the screen or page.
This tutorial manual provides a comprehensive introduction to R, a software package for statistical computing and graphics. R supports a wide range of statistical techniques and is easily extensible via user-defined functions. One of R´s strengths is the ease with which publication-quality plots can be produced in a wide variety of formats. This is a printed edition of the tutorial documentation from the R distribution, with additional examples, notes and corrections. It is based on R version 2.9.0, released April 2009. R is free software, distributed under the terms of the GNU General Public License (GPL). It can be used with GNU/Linux, Unix and Microsoft Windows. All the money raised from the sale of this book supports the development of free software and documentation.
Visualizing the data is an essential part of any data analysis. Modern computing developments have led to big improvements in graphic capabilities and there are many new possibilities for data displays. This new volume in the series Springer Handbooks of Computational Statistics gives an overview of modern data visualization methods, both in theory and practice. There are definitive chapters on modern graphical tools such as mosaic plots, parallel coordinate plots and linked views. There are chapters dedicated to graphical methodology for particular areas of statistics, for example Bayesian analysis, genomic data and cluster analysis, as well as chapters on software for graphics. Specialists from all over the world have contributed papers on their areas of expertise.
Ghost stories by M. R. James are pretty varied, and based on the genre of Gothic novels. The plot of ´´Oh, Whistle, and I´ll Come to You, My Lad´´ is unveiled when Professor Parkins finds a whistle engraved with a Latin inscription... and blows it. ´´The School Story´´, builds a mystic and fearsome atmosphere around a mysterious Byzantine coin. Once again, well-chosen voices, superb music, and original cover-graphics serve to enhance the feel of the stories. 1. Language: English.

This is the perfect study guide to the complete works of Shakespeare, covering everything from the romantic comedy of Romeo and Juliet to the tragedy Macbeth, alongside his Elizabethan history plays, sonnets, and other poems With detailed plot summaries and an in-depth analysis of the major characters and themes, this is a brilliant, innovative exploration of the entire canon of Shakespeare plays, sonnets and poetry, from the comedies of Twelfth Night and As You Like It to the tragedies of Julius Caesar and Hamlet, plus lost plays and lesser known works of poetry. Packed with witty illustrations and memorable quotes, The Shakespeare Book brings the Bard´s best-loved characters and storylines to life, and explores all of his key themes and much-quoted phrases. Easy-to-understand graphics and illustrated timelines also offer an at-a-glance summary of each play. Whether you´re a Shakespeare scholar, a student of the great Bard, or simply someone who wants to learn more, The Shakespeare Book offers a fuller appreciation of his phenomenal talent and the lasting legacy of his plays and poetry.
The night the first Mars Exploration Rover landed, the engineering team at the Jet Propulsion Laboratory in Pasadena excitedly announced: ´´We have excellent quaternions for the rover!´´ This meant that through the application of a technique developed 160 years before they were able to determine the precise orientation of the spacecraft on Mars after traveling millions of miles through space. Quaternions are widely used in computer graphics, simulations, Hollywood special effects, computer games, and space travel, but they are conceptually very hard to grasp. The computer graphics community has a general familiarity with quaternions and their uses, but there are still many unresolved issues and controversies with them. And the subject mystifies many new engineers, such as game developers who lack a background in mathematics. While there are books that approach quaternions from a mathematician´s perspective, this is the first that will give a professional developer an intuitive understanding of quaternions through visual representations. Visualizing Quaternions introduces new developers to this powerful technique and will provide the definitive explanation to those who have been struggling to use them. 1558600210LangtextGame development is still in its infancy, but games are poised for a major evolution: Ready to move from mostly plot-driven stories to more character based ones. The problem is that the principles of sophisticated character design and interaction are not widely understood in the game development community. And gender and cultural issues within the game genre are growing in importance. Katherine Isbister has spent 10 years examining what makes interactions with computer characters useful and engaging to different audiences. The key is to understand what´s memorable, exciting, useful, and engaging to the participant about real-life social interactions, and applying that to character design. Game designers who create great characters often make use of these principles without realizing it. This book gives game design professionals and other designers a framework for how social roles and perceptual manipulations function, so that they are more aware of what they are doing when they design characters, and why it works.
