Ce livre est né comme une introduction à la R et avec l’intention d’être un guide pratique pour apprendre les premières étapes de R. Dans le premier chapitre, nous allons commencer à parler des structures de R, des vecteurs, des matrices, des listes, et dataframe. Nous allons voir comment créer des objets en R et comment utiliser les premières fonctions de R, par exemple pour réorganiser un vecteur ou ajouter des colonnes à une matrice. Dans le deuxième chapitre, nous parlerons de la façon de mettre en place notre environnement de travail de R, comment installer et charger en mémoire un package, comment créer et extraire des sous-ensembles de données, supprimer les données en double, et gérer les dates. Le troisième chapitre est consacré à importer des données de R, différents formats, principalement le .csv, mais aussi des données dans Excel, txt et sav. Dans le quatrième chapitre, nous parlerons de la façon de manipuler nos données grâce à des fonctions et des packages spécifiques, par exemple dplyr. Dans le cinquième chapitre on traitera un peu de statistique sur R, et dans le sixième de la création de diagrammes, soit avec les fonctions de base de R, soit avec de packages spécifiques, en particulier ggplot2. Enfin, dans le septième chapitre, nous apprendrons à créer des rapports dans R, en utilisant Markdown et Knitr.

Hugely successful and popular text presenting an extensive and comprehensive guide for all R users The R language is recognized as one of the most powerful and flexible statistical software packages, enabling users to apply many statistical techniques that would be impossible without such software to help implement such large data sets. R has become an essential tool for understanding and carrying out research. This edition: Features full colour text and extensive graphics throughout. Introduces a clear structure with numbered section headings to help readers locate information more efficiently. Looks at the evolution of R over the past five years. Features a new chapter on Bayesian Analysis and Meta-Analysis. Presents a fully revised and updated bibliography and reference section. Is supported by an accompanying website allowing examples from the text to be run by the user. Praise for the first edition: ‘…if you are an R user or wannabe R user, this text is the one that should be on your shelf. The breadth of topics covered is unsurpassed when it comes to texts on data analysis in R.’ (The American Statistician, August 2008) ‘The High-level software language of R is setting standards in quantitative analysis. And now anybody can get to grips with it thanks to The R Book…’ (Professional Pensions, July 2007)

Cet ouvrage propose une approche pédagogique complète de la programmation vectorielle avec R aussi bien pour les utilisateurs débutants que pour ceux sachant déjà programmer dans un autre langage. Les chapitres sont courts, avec de nombreux exemples et des exercices progressifs dont les corrigés sont détaillés. Les exemples et exercices sont appliqués aux domaines des sciences de la vie et de la santé, des mathématiques et de l'économie et sont volontairement simples (recherche de la plus grande valeur, recherche de mots, lecture de fichiers Excel) de façon à ne pas ajouter la difficulté de compréhension des calculs aux difficultés de la programmation. Cet ouvrage est un outil indispensable à toute personne qui veut progresser en R ou qui a besoin d'automatiser des traitements, qu'il s'agisse de lectures de fichiers, de calculs ou de graphiques. L'ensemble des lignes de code des exercices est téléchargeable sur le site dunod.com.

Learn how to use R to turn raw data into insight, knowledge, and understanding. 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
