cache_metadata_file_name()

cache_metadata_file_path()

cache_metadata_read()

cache_metadata_write(metadata)

cache_metadata_append_or_replace(hash, working.dir, input.file.path)

cache_metadata_refresh()

cache_hash(df)

cache_clean_hash(hash)

cache_clean_all()

hash	⁠[character]⁠ (no default) Hash of an input dataset.
working.dir	⁠[character]⁠ (no default) Path to directory to include in metadata.
input.file.path	⁠[character]⁠ (no default) Path to input file (which must exist) to include in metadata.
