validate 0.9.3 is on CRAN

CRAN just accepted the latest version of our R package validate.

The validate package provides an infrastructure to perform any data quality check in a flexible and extensible way.

This is a minor update with the following new features:

• New functions exists_any and exists_one to help define cross-record validation rules (thanks to David Salgado)
• results of sort and aggregate now include key columns (if any)
• Added JSS paper and CITATION file.

We are also very happy to report that our paper on validate has been accepted by the Journal of Statistical Software. It will take a while before it is published but a preprint was added as a vignette.
