taxon_views: Management of concept views in taxonomic lists.

Description

Retrieve or replace slot taxonViews in an object of class '>taxlist.

Usage

# S4 method for taxlist
taxon_views(taxlist, ...)
taxon_views(taxlist) <- value
# S4 method for taxlist
add_view(taxlist, ...)

Arguments

taxlist

A '>taxlist object.

value

An object of class 'data.frame' containing the references used to define the circumscription of taxon concepts included in 'taxlist'.

...

Further arguments to be passed among methods.

Value

An object of class '>taxlist with added views.

Details

Taxon views indicate in '>taxlist objects the references determining the circumscription of the respective taxon concepts. When adding a new concept (see add_concept), the respective reference may not yet occur in the input '>taxlist object.

The term ‘taxon view’ was introduced by Zhong et al. (1996) and corresponds to the reference used for the definition of a concept.

This function retrieves the slot 'taxonViews' from objects of the class '>taxlist.

The replacement method 'taxon_views<-' replaces the whole content of slot 'taxonViews' and it is only recommended to use when constructing a new '>taxlist object from an empty prototype.
