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.
