The cut-and-paste approach to writing statistical reports is not only tedious and laborious, but also can be harmful to scientific research, because it is inconvenient to reproduce the results. Dynamic Documents with R and knitr introduces a new approach via dynamic documents, i.e. integrating computing directly with reporting. A comprehensive guide to the R package knitr, the book covers examples, document editors, basic usage, detailed explanations of a wide range of options, tricks and solutions, extensions, and complete applications of this package. The book provides an overview of dynamic documents, introducing the idea of literate programming. It then explains the importance of dynamic documents to scientific research and its impact on reproducible research. Building on this, the author covers basic concepts, common text editors that support knitr, and the syntax for different document formats such as LaTeX, HTML, and Markdown before going on to discuss core functionality, how to control text and graphics output, caching mechanisms that can reduce computation time, and reuse of source code. He then explores advanced topics such as chunk hooks, integrating other languages such as Python and awk into one report in the knitr framework, and useful tricks that make it easier to write documents with knitr. Discussions of how to publish reports in a variety of formats, applications, and other tools complete the coverage. Suitable for both beginners and advanced users, this book shows you how to write reports in simple languages such as Markdown. The reports range from homework, projects, exams, books, blogs, and web pages to any documents related to statistical graphics, computing, and data analysis. While familiarity with LaTeX and HTML is helpful, the book requires no prior experience with advanced programs or languages. For beginners, the text provides enough features to get started on basic applications. For power users, the last several chapters enable an understanding of the extensibility of the knitr package.

Diese für Studierende ebenso wie für Wissenschaftler, Ingenieure und Praktiker geeignete Einführung in mathematische Modellbildung und Simulation setzt nur einfache Grundkenntnisse in Analysis und linearer Algebra voraus – alle weiteren Konzepte werden im Buch entwickelt. Die Leserinnen und Leser lernen anhand detailliert besprochener Beispiele aus unterschiedlichsten Bereichen (Biologie, Ökologie, Ökonomie, Medizin, Landwirtschaft, Chemie, Maschinenbau, Elektrotechnik, Prozesstechnik usw.), sich kritisch mit mathematischen Modellen auseinanderzusetzen und anspruchsvolle mathematische Modelle selbst zu formulieren und zu implementieren. Das Themenspektrum reicht von statistischen Modellen bis zur Mehrphasen-Strömungsdynamik in 3D. Für alle im Buch besprochenen Modellklassen wird kostenlose Open-Source-Software zur Verfügung gestellt. Grundlage ist das eigens für dieses Buch entwickelte Betriebssystem Gm.Linux („Geisenheim-Linux“), das ohne Installationsaufwand z.B. auch auf Windows-Rechnern läuft. Ein Referenzkartensystem zu Gm.Linux mit einfachen Schritt-für-Schritt-Anleitungen ermöglicht es, auch komplexe statistische Berechnungen oder 3D-Strömungssimulationen in kurzer Zeit zu realisieren. Alle im Buch beschriebenen Verfahren beziehen sich auf Gm.Linux 2.0 (und die darin fixierten Versionen aller Anwendungsprogramme) und sind daher unabhängig von Softwareaktualisierungen langfristig verwendbar. Aus dem Inhalt: • Grundlagen mathematischer Modellbildung und Simulation • Phänomenologische und mechanistische Modelle • Statistik, Stochastik und Diff erentialgleichungen (ODE‘s und PDE‘s) • Open Source Software: OpenFOAM, R, Maxima, Six Sigma, Versuchsplanung, Prozessoptimierung, Klassifi kation, PCA, MCA, Datenbanken, Big Data, Random-Forest, Entscheidungsbäume, Gm.HYDRA usw. • Betriebssystem Gm.Linux • Gastbeiträge aus Industrie und Forschung

Learn how to perform data analysis with the R language and software environment, even if you have little or no programming experience. With the tutorials in this hands-on guide, you’ll learn how to use the essential R tools you need to know to analyze data, including data types and programming concepts. The second half of Learning R shows you real data analysis in action by covering everything from importing data to publishing your results. Each chapter in the book includes a quiz on what you’ve learned, and concludes with exercises, most of which involve writing R code. Write a simple R program, and discover what the language can do Use data types such as vectors, arrays, lists, data frames, and strings Execute code conditionally or repeatedly with branches and loops Apply R add-on packages, and package your own work for others Learn how to clean data you import from a variety of sources Understand data through visualization and summary statistics Use statistical models to pass quantitative judgments about data and make predictions Learn what to do when things go wrong while writing data analysis code

R ist eine objekt-orientierte und interpretierte Sprache und Programmierumgebung für Datenanalyse und Grafik - frei erhältlich unter der GPL. Ziel dieses Buches ist es, nicht nur ausführlich in die Grundlagen der Sprache R einzuführen, sondern auch ein Verständnis der Struktur der Sprache zu vermitteln. Leicht können so eigene Methoden umgesetzt, Objektklassen definiert und ganze Pakete aus Funktionen und zugehöriger Dokumentation zusammengestellt werden. Die enormen Grafikfähigkeiten von R werden detailliert beschrieben. Das Buch richtet sich an alle, die R als flexibles Werkzeug zur Datenenalyse und -visualisierung einsetzen möchten: Studierende, die Daten in Projekten oder für ihre Diplomarbeit analysieren möchten, Forschende, die neue Methoden ausprobieren möchten, und diejenigen, die in der Wirtschaft täglich Daten aufbereiten, analysieren und anderen in komprimierter Form präsentieren.

bookdown: Authoring Books and Technical Documents with R Markdown presents a much easier way to write books and technical publications than traditional tools such as LaTeX and Word. The bookdown package inherits the simplicity of syntax and flexibility for data analysis from R Markdown, and extends R Markdown for technical writing, so that you can make better use of document elements such as figures, tables, equations, theorems, citations, and references. Similar to LaTeX, you can number and cross-reference these elements with bookdown. Your document can even include live examples so readers can interact with them while reading the book. The book can be rendered to multiple output formats, including LaTeX/PDF, HTML, EPUB, and Word, thus making it easy to put your documents online. The style and theme of these output formats can be customized. We used books and R primarily for examples in this book, but bookdown is not only for books or R. Most features introduced in this book also apply to other types of publications: journal papers, reports, dissertations, course handouts, study notes, and even novels. You do not have to use R, either. Other choices of computing languages include Python, C, C++, SQL, Bash, Stan, JavaScript, and so on, although R is best supported. You can also leave out computing, for example, to write a fiction. This book itself is an example of publishing with bookdown and R Markdown, and its source is fully available on GitHub.
