FCMapper-package: Fuzzy Cognitive Mapping
In FCMapper: Fuzzy Cognitive Mapping

Description Details Author(s) References

This package provides several functions to create and manipulate fuzzy cognitive maps.It is based on FCMapper for Excel, distributed at http://www.fcmappers.net/joomla/, developed by Michael Bachhofer and Martin Wildenberg.

Maps are inputted as adjacency matrices. Attributes of the maps and the equilibrium values of the concepts (including with user-defined contrained values) can be calculated. The maps can be graphed with a function that calls "igraph". Multiple maps with shared concepts can be aggregated.

Functions:

-changes.scenario: Finds equilibrium values of concepts with no fixes values.

-check.matrix: Checks that fuzzy cognitive map is square and values are between -1 and 1.

-combine.maps: Aggregates multiple fuzzy cognitive maps into one.

-comp.scenarios: Compares the equilibrium values of two scenarios.

-comp.maps: Calculates similarity indices (S2 and Jaccard) of two coginitive maps.

-concept.indices: Calculated concept-level indices.

-graph.fcm: Plots fuzzy cognitive map by calling igraph package

-matrix.indices: Calculates matrix-level indices.

-nochanges.scenario: Finds equilibrium values of concepts with user-defined fixed values.
