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)

Qu'est-ce que R : un langage de programmation ou un logiciel de statistique ? Les deux réponses peuvent être données, chacun répondant selon son utilisation de R. Mais un statisticien souhaitant développer de vraies compétences en R se doit d'en maîtriser les deux aspects. Ce livre est donc structuré en deux parties correspondant à ces deux potentiels de R. La première partie concerne la programmation avec R : les commandes de base pour la création et la manipulation d'objets, la gestion des entrées/sorties, la programmation et les graphiques. Les derniers chapitres traitent des aspects plus avancés de la programmation avec, par exemple, l'utilisation de fonctions écrites en C ou en Fortran dans un script R, ou bien la création de package. La seconde partie porte sur les méthodes statistiques, présentes essentiellement dans la version de base de R, mais aussi dans certains packages spécifiques : statistiques descriptives, inférence statistique et méthodes non-paramétriques, tests statistiques (comparaison d'échantillon, test d'adéquation, etc.), régression linéaire et analyse de la variance, séries temporelles, analyse de durées de vie, analyse de données et méthodes de classification. Cette partie est complétée par un chapitre sur la génération automatique de rapports.
