Combine selected entries in a taxon-range table to remove duplicates

Description

Combine selected entries in a taxon-range table to remove duplicates

Usage

synonymize(x, table = NULL, ids = table$tna, max = table$max, min = table$min)

Arguments

x

Indices or values (taxon names) to combine

table

Taxon-range table

ids

Vector or column of taxon names (used for matching taxon names in x). Defaults to table$tna

max

Vector or column containing maximum ages

min

Details

This function is meant as an aid to manually editing species tables and remove synonyms or incorrect spellings of taxonomic name that result in an inflated number of distinct taxa being represented.

Value

A data.frame containing taxon names, maximum, minimum and mean ages, with ranges for the selected entries merged and superfluous entries removed (note that the first taxon indicated by x is kept as valid).

Examples

data(archosauria)
sp<-archosauria$sptab_Stegosauria

synonymize(grep("stenops",sp$tna),sp)->sp
synonymize(c("Hesperosaurus mjosi","Stegosaurus mjosi"),sp)->sp
