Riassunto
Newcomers to R are often intimidated by the command-line interface, the vast number of functions and packages, or the processes of importing data and performing a simple statistical analysis. The R Primer provides a collection of concise examples and solutions to R problems frequently encountered by new users of this statistical software. This new edition adds coverage of R Studio and reproducible research.
Testo aggiuntivo
"This is an extremely well-written book that thoroughly covers the subject and offers a significant number of examples that are explained very clearly. It will certainly be a beneficial resource for all R users. This reviewer teaches an online course in statistics using R, and believes that this text will serve as a very effective reference."~R. Bharath, Northern Michigan University
"This book is intended for readerswho are familiarwith statistics and already have some basic knowledge in R. It provides a collection of more than 170 examples or problems and solutions in an R-context, derived from questions the author encountered in the statistical consultancy service of the University of Copenhagen. The problems concern data import and data management, statistical analysis and graphical presentation. Each problem or example is stated in one sentence. The solution is self-contained and provides an R code that can be run by the reader so that the results can be replicated; related problems can then be dealt with by adapting the R code for the needs at hand. Alternative solutions are also indicated at the end of most entries."~Peter Hackl, Stat Papers
