comp.scenarios: Scenario comparison

In FCMapper: Fuzzy Cognitive Mapping

Description

The equilibrium values of two scenarios are compared.

Usage

comp.scenarios(scenario1, scenario2)

Arguments

scenario1	Dataframe output from nochanges.scenario or changes.scenario.
scenario2	Dataframe output from nochanges.scenario or changes.scenario.

Value

The difference between the equilibrium values of the two scenarios are given in a data frame along with the concept names, the scenario 1 values, the scenario 2 values, and the percent difference.

Note

The scenarios must be scenarios of fuzzy cognitive maps with the same concepts, though not neccesarily the same edges.

Examples

matrix = matrix(nrow=7,ncol=7)
matrix[1,] = c(0,-0.5,0,0,1,0,1)
matrix[2,] = c(1,0,1,0.2,0,0,0.6)
matrix[3,] = c(0,1,0,0,0,0,0)
matrix[4,] = c(0.6,0,0,1,0,0,0.1)
matrix[5,] = c(0,0.5,0,0,1,0,-0.6) 
matrix[6,] = c(0,0,-1,0,0,0,0)
matrix[7,] = c(0,0,0,-0.5,0,0,1)
concept.names = c("A","B","C","D","E","F","G")

scenario1 = nochanges.scenario(matrix,iter=25,concept.names)

scenario2 = changes.scenario(matrix,concept.names,iter=25,set.concepts=c("B"),set.values=c(0.5))
