Rename relational data attributes

Generic function, for renaming attributes present in a database-like structure.

Usage

rename_attrs(x, names, ...)

Arguments

x

an object with an attrs_order attribute. This includes relational schema objects, such as a relation_schema or database_schema object, relational data objects, such as a relation or database object, and functional_dependency objects.

names

a character vector of the same length as attrs_order(x), with no duplicated elements, to be used as the new attribute names.

...

further arguments passed on to methods.

Value

A relational object of the same type as x, with attributes renamed consistently across the whole object.

Details

This function has a different intended use to re-assigning attrs_order: that is intended only for rearranging the order of the attributes, without renaming them. This is intended for renaming the attributes without re-ordering them.
