In delimtools: Helper Functions for Species Delimitation Analysis

Compute Agreement Between Alternative Species Delimitation Partitions

Description

match_ratio() uses the Match Ratio statistic of Ahrens et al. (2014) to compute agreement between all pairs of species delimitation partitions in delim_join output.

Usage

match_ratio(delim)

Arguments

delim

Output from delim_join.

Details

match_ratio() iterates between all species delimitation partitions in delim_join output and returns a tbl_df containing the following columns:

• pairs pairs of species delimitation methods analyzed.

• delim_1 number of species partitions in method 1.

• delim_2 number of species partitions in method 2.

• n_match number of identical species partitions in methods 1 and 2.

• match_ratio match ratio statistic, where 0 indicates no agreement between pairs of species delimitation partitions and 1 indicates complete agreement between them.

Value

an object of class tbl_df.
