DDI with R

Description

This is a package to collect data and metadata from a variety of sources, and convert those into some of the most popular statistical packages: Stata, SAS, SPSS, and naturally R.

The biggest strength of this package is its ability to convert to and from a DDI (Data Documentation Initiative) Codebook.

Handling missing values

The problem of the missing values is was a recurrent one in R, with various solutions having been implemented in various places. The base package offers a single (empty, undeclared) type of missing value, the NA.

In many sciences, however, there are multiple reasons for missing values, and those are not covered by the NA.
A dedicated package was written to solve this, called declared, which is used by DDIwR.

Graphical user interface

Package DDIwR benefits from a cross-platform GUI called StatConverter. It is similar to a popular commercial software, but built on top of R.

Windows users can already download the setup installer (including R, embedded in the application), or download a .zip file containing all application files to start the application without installing it. More versions for different other operating systems will soon be added.
