Yamlet

R datasets of modest size are routinely stored as flat files and retrieved as data frames. The classic storage formats (comma delimited, tab delimited) do not have obvious mechanisms for storing data about the data: i.e., metadata such as column labels, units, and meanings of categorical codes. In many cases we hold such information in our heads and hard-code it in our scripts as axis labels, figure legends, or table enhancements. That’s probably fine for simple cases but does not scale well in production settings where the same metadata is re-used extensively. Is there a better way to store, retrieve, and bind table metadata for consistent reuse?

Yamlet is a YAML-based mechanism for working with table metadata. Supports compact syntax for creating, modifying, viewing, exporting, importing, displaying, and plotting metadata coded as column attributes. etc.

It provides a flexible environment to store and apply metadata such as column labels, units, and meanings of categorical codes for consistent tabulation and plotting.
