rWCVP (version 1.2.4)

wcvp_match_fuzzy: Fuzzy (approximate) matching to the WCVP.

Description

Fuzzy matching to names in the WCVP using phonetic matching and edit distance. The WCVP can be loaded for matching from rWCVPdata::wcvp_names.

Usage

wcvp_match_fuzzy(names_df, wcvp_names, name_col, progress_bar = TRUE)
phonetic_match(names_df, wcvp_names, name_col)
edit_match(names_df, wcvp_names, name_col)

Value

Match results from WCVP bound to the original data from names_df.

Arguments

names_df

Data frame of names for matching.

wcvp_names

Data frame of taxonomic names from WCVP version 7 or later. If NULL (the default), names will be loaded from rWCVPdata::wcvp_names.

name_col

Character. The column in names_df that has the taxon name for matching.

progress_bar

Logical. Show progress bar when matching? Defaults to TRUE; should be changed to FALSE if used in a markdown report.

Details

The wcvp_match_fuzzy function uses phonetic matching first and then finds the closest match based on edit distance for any remaining names.

Phonetic matching uses phonics::metaphone encoding with a maximum code length of 20.

Edit distance matching finds the closest match based on Levenshtein similarity, calculated by RecordLinkage::levenshteinSim.
