Export a match sample to CSV for manual labelling

Write a sampled set of matches to a CSV pre-filled with an equal column on block-header rows. Users edit the CSV in any spreadsheet, marking only exceptions (e.g. false positives) and leaving the rest as defaults.

Block definition follows the matches schema: for candidate matches (from search_candidates()), the header is the base-side row and candidate rows inherit its default. For duplicate matches (from detect_duplicates()), the header is the rank-1 row and the remaining records in the duplicate group inherit its default.

Usage

export_for_labelling(sample, file, default_label = 1L)

Arguments

sample

A Match_Sample object or a data.table / data.frame with the matches schema.

file

Path to the CSV file to write.

default_label

Integer scalar (default 1L) used as the block-default equal value on header rows. 0L for the inverse workflow.

Value

Invisibly returns file.
