⚠️There's a newer version (1.1.7) of this package.Take me there.

validate (version 1.0.1)

Data Validation Infrastructure

Description

Declare data validation rules and data quality indicators; confront data with them and analyze or visualize the results. The package supports rules that are per-field, in-record, cross-record or cross-dataset. Rules can be automatically analyzed for rule type and connectivity. See also Van der Loo and De Jonge (2018) , chapter 6.
