Label Management

These functions work on a vector of character strings storing bi- or trinomial species names, typically ``Genus_species_subspecies''.

Usage
label2table(x, sep = NULL, as.is = FALSE)
stripLabel(x, species = FALSE, subsp = TRUE, sep = NULL)
abbreviateGenus(x, genus = TRUE, species = FALSE, sep = NULL)
Arguments
x

a vector of mode character.

sep

the separator (a single character) between the taxonomic levels (see details).

as.is

a logical specifying whether to convert characters into factors (like in read.table).

species, subsp, genus

a logical specifying whether the taxonomic level is concerned by the operation.

Details

label2table returns a data frame with three columns named ``genus'', ``species'', and ``subspecies'' (with NA if the level is missing).

stripLabel deletes the subspecies names from the input. If species = TRUE, the species names are also removed, thus returning only the genus names.

abbreviateGenus abbreviates the genus names keeping only the first letter. If species = TRUE, the species names are abbreviated.

By default, these functions try to guess what is the separator between the genus, species and/or subspecies names. If an underscore is present in the input, then this character is assumed to be the separator; otherwise, a space. If this does not work, you can specify sep to its appropriate value.

Value

A vector of mode character or a data frame.
