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)

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).

Arguments

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.

Examples

data(archosauria)
sp<-archosauria$sptab_Stegosauria
synonymize(c(32,33),sp)->sp
synonymize(grep("stenops",sp$tna),sp)->sp
