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

Arguments

x

An R object of class kstructure or kbase.

...

Currently not used.

Details

as.relation takes an arbitrary knowledge structure and computes its underlying surmise relation, i.e., the set of item paris corresponding to the knowledge dependencies. Antisymmetric and transitive surmise relations may then be plotted as a Hasse diagram.

Value

An R object of class relation.
