Fuzzy Cognitive Mapping
Description
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.
