Details

To obtain whether or not taxonomic names are autonyms we compare the words either side of a 'splitter'. The splitters are defined to be any of subsp., var., f., ssp. or nothosubsp.. If the words either side are identical we return TRUE otherwise we return FALSE.

Examples

is_autonym("Codiaeum variegatum var. variegatum")
#> [1] TRUE
is_autonym("Crinum pedunculatum f. purple")
#> [1] FALSE

taxon_names = c("Saintpaulia diplotricha", "Codiaeum variegatum var. variegatum")
collection = data.frame(ID = 1:2, name = taxon_names)
add_is_autonym(collection, taxon_name_column = 'name')
#>   ID                                name is_autonym
#> 1  1             Saintpaulia diplotricha      FALSE
#> 2  2 Codiaeum variegatum var. variegatum       TRUE
