Opis: Using R and Rstudio for Data Management, Statistical Analysis and Graphics - Ken Kleinman, Nicholas Horton

Improve Your Analytical Skills Incorporating the latest R packages as well as new case studies and applications, Using R and RStudio for Data Management, Statistical Analysis, and Graphics, Second Edition covers the aspects of R most often used by statistical analysts. New users of R will find the book's simple approach easy to understand while more sophisticated users will appreciate the invaluable source of task-oriented information. New to the Second Edition * The use of RStudio, which increases the productivity of R users and helps users avoid error-prone cut-and-paste workflows * New chapter of case studies illustrating examples of useful data management tasks, reading complex files, making and annotating maps, "scraping" data from the web, mining text files, and generating dynamic graphics * New chapter on special topics that describes key features, such as processing by group, and explores important areas of statistics, including Bayesian methods, propensity scores, and bootstrapping * New chapter on simulation that includes examples of data generated from complex models and distributions * A detailed discussion of the philosophy and use of the knitr and markdown packages for R * New packages that extend the functionality of R and facilitate sophisticated analyses * Reorganized and enhanced chapters on data input and output, data management, statistical and mathematical functions, programming, high-level graphics plots, and the customization of plots Easily Find Your Desired Task Conveniently organized by short, clear descriptive entries, this edition continues to show users how to easily perform an analytical task in R. Users can quickly find and implement the material they need through the extensive indexing, cross-referencing, and worked examples in the text. Datasets and code are available for download on a supplementary website. "... the book is easy to use. I have had it on my desk for the past few weeks and it has become invaluable. For those, like me, who find themselves regularly switching between R, MATLAB, and Python-or similar packages-it can save a lot of time." -Significance Magazine, February 2016 Praise for the First Edition: This book is an excellent reference resource. Used this way, it can be helpful for years to come for both experienced and novice users. The organization of the material makes it easy to find the relevant piece of information either by topic (from the table of contents) or using one of the indexes. The task entries are self-contained. Users with experience in technical computing may use it as a quick starter in R, as well. -Georgi N. Boshnakov, Journal of Applied Statistics, June 2012 This book provides a concise reference and annotated examples for R ... . It is needed because R does not come with a coordinated manual ... It is much easier to find information in Horton and Kleinman's book because of their more detailed indices and table of contents. ... Horton and Kleinman have succeeded very well in their goal of providing a concise reference manual and annotated examples. If you know the statistics (or can look them up) and have some experience using R, it is an extremely useful reference, and it has become my most consulted R book. ... it would be an excellent reference for those wanting look up the syntax of a command together with an example of how to use it. It is also very useful if you cannot remember the command and want to know how to do it in R. -Paul H. Geissler, The American Statistician, November 2011 The interesting aspect of the book is that it does not only describe the basic statistics and graphics function of the basic R system but it describes the use of 40 additional available from the CRAN website. The website contains also the R code to install all the packages that contain the described features. In summary, the book is a useful complement to introductory statistics books and lectures ... Those who know R might get additional hints on new features of statistical analyses. -International Statistical Review (2011), 79Data Input and Output Input Output Further resources Data Management Structure and metadata Derived variables and data manipulation Merging, combining, and subsetting datasets Date and time variables Further resources Examples Statistical and Mathematical Functions Probability distributions and random number generation Mathematical functions Matrix operations Examples Programming and Operating System Interface Control flow, programming, and data generation Functions Interactions with the operating system Common Statistical Procedures Summary statistics Bivariate statistics Contingency tables Tests for continuous variables Analytic power and sample size calculations Further resources Examples Linear Regression and ANOVA Model fitting Tests, contrasts, and linear functions of parameters Model results and diagnostics Model parameters and results Further resources Examples Regression Generalizations and Modeling Generalized linear models Further generalizations Robust methods Models for correlated data Survival analysis Multivariate statistics and discriminant procedures Complex survey design Model selection and assessment Further resources Examples A Graphical Compendium Univariate plots Univariate plots by grouping variable Bivariate plots Multivariate plots Special-purpose plots Further resources Examples Graphical Options and Configuration Adding elements Options and parameters Saving graphs Simulation Generating data Simulation applications Further resources Special Topics Processing by group Simulation-based power calculations Reproducible analysis and output Advanced statistical methods Further resources Case Studies Data management and related tasks Read variable format files Plotting maps Data scraping Text mining Interactive visualization Manipulating bigger datasets Constrained optimization: the knapsack problem Appendix A: Introduction to R and RStudio Appendix B: The HELP Study Dataset Appendix C: References Appendix D: Indices
