Export the column matching log to CSV files — export_match

Takes the result of match_columns() and writes two files: a per-dataset match log and (optionally) an issues log from clean_dataset(). A master log that accumulates entries across all datasets is also updated.

Usage

export_match_log(
  match_result,
  issues_dt = NULL,
  dataset_label = "",
  year_tag = NA,
  log_dir = "logs/matching",
  append_master = TRUE
)

Arguments

match_result: List returned by match_columns().
issues_dt: data.table of issues from clean_dataset(), or NULL to skip the issues log.
dataset_label: Human-readable label (used in filenames and metadata).
year_tag: Integer year for traceability. Default NA.
log_dir: Directory where CSV logs are written. Created if absent.
append_master: If TRUE (default), updates the master log CSV.

Value

The annotated log data.table for this dataset, invisibly.
