Function to perform Galois derivations between partially ordered subsets
Usage
galois(x, labeling = c("full", "reduced"))
Arguments
x
a data frame with objects and attributes
labeling
whether the derivations should be with full or reduced labeling
Value
A labelled list with Galois derivations of objects and attributes
Details
Galois derivations (or connections) are mappings between families of partially ordered subsets, which are useful to analyse the structure of both sets. Subsets are typically the actors in a social network and their corresponding affiliations and events, i.e. two-mode networks, or else a group of objects with a list of different attributes used in formal concept analysis.
