One of the aims of this package is to make life easier for useRs who deal with survey data sets. It provides an infrastructure for the management of survey data including value labels, definable missing values, recoding of variables, production of code books, and import of (subsets of) SPSS and Stata files. Further, it provides functionality to produce tables and data frames of arbitrary descriptive statistics and (almost) publication-ready tables of regression model estimates. Also some convenience tools for graphics, programming, and simulation are provided. Downloads: Reverse dependencies:
Welcome to the ' R' programming Wikibook This book is designed to be a practical guide to the R programming language  . R is free software designed for statistical computing. There is already great documentation for the standard R packages on the CRAN website  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 knowledge and tricks on R . It is supposed to be organized by task but not by discipline  .
