R programming wikibooks
This book is designed to be a practical guide to the R programming language[1]. R is free software designed for statistical computing. There is already great documentation for the standard R packages on the CRAN website[2] and also a coverage of add-on packages on CRAN task views, but all of these resources are scattered and therefore difficult to find and to compare. The aim of this Wikibook is to be the place where anyone can share his/her knowledge and tricks on R. It is supposed to be organized by task but not by discipline[3]. We try to make a cross-disciplinary book, ie a book that can be used by all people applying statistics to some specific fields.
