as.relation: Surmise Relations of Knowledge Structures

In kst: Knowledge Space Theory

Surmise Relations of Knowledge Structures

Description

Computes the surmise relation of knowledge structures.

Usage

  ## S3 method for class 'kstructure'
as.relation(x, ...)
  ## S3 method for class 'kbase'
as.relation(x, ...)
  ## S3 method for class 'kfamset'
as.relation(x, ...)

Arguments

x	An R object of class kstructure, kbase, or kfamset.
...	Currently not used.

Details

as.relation takes an arbitrary knowledge structure and computes the surmise relation of the corresponding quasi-ordinal knowledge space. Antisymmetric (and transitive) surmise relations may then be plotted as a Hasse diagram.

Value

An R object of class relation.
