Data for an illustrative graphic:

Description

Create a dataframe that can be used as input for an illustrative plot. Useful for describing the Allen operators: illustrate the full set of Allen relations, concurrent Allen relations, and relations with distinct endpoints (six-value set). Also, useful for describing the chronological domains of stratification, anagenesis, cladogenesis, reticulation, and incorporation.

Usage

illustrate_allen_relations(relations = "basic")

Arguments

relations

One of:

basic

show the 13 basic Allen relations (default);

concurrent

show concurrent relations;

six

show relations with distinct endpoints;

inherit

show chronological information about a transmission relationship from the receiver's point of view;

contribute

show chronological information from the giver's point of view during transmission;

stratigraphic

show the basic stratigraphic relations established by an observation of superposition;

anagenetic

show the basic relations of artifact change without branching;

cladogenetic

show the basic relations of artifact change with branching;

contributors

show the composite relations of two contributors to a reticulation occurrence;

innovations

show the composite relations of two entities produced by innovation from a single source;

sequence

show the composite relations of superposition in a stratigraphic sequence; or

anagenesis

show the composite relations of transmission during anagenesis.

Value

A dataframe for input to allen_plot()
