match_any_linker: match_any_linker

Description

Linking functions return a logical vector, with the TRUE elements indicating rows in the data that are linked.

Usage

match_any_linker(from_data, to_data = from_data)

Arguments

from_data

A data.frame-like object containing the keys for linking the corresponding rows to rows in to_data

to_data

A data.frame-like object containing the keys that will be matched against the keys in from_data

Value

a logical vector, indicating which from_data rows are linked

Details

The match_any_linker function links rows in from_data to rows in to_data that share the same key.

By convention, a key is defined as the combination of the values in every column of from_data and to_data. Thus, from_data and to_data should contain only the columns necessary for key generation. They should not be an entire dataset.
