Data Validation Infrastructure

Description

Data often suffer from errors and missing values. A necessary step before data analysis is verifying and validating your data. Package validate is a toolbox for creating validation rules and checking data against these rules.

Getting started

The easiest way to get started is through the examples given in check_that.

The general workflow in validate follows the following pattern.

• Define a set of rules or quality indicator using validator or indicator.

• confront data with the rules or indicators,

• Examine the results either graphically or by summary.

There are several convenience functions that allow one to define rules from the commandline, through a (freeform or yaml) file and to investigate and maintain the rules themselves. Please have a look at the cookbook for a comprehensive introduction.
