Arguments

object

RapResults, or RapSolved object.

not used.

Value

data.frame

Details

This table follows Marxan conventions (summary.dat in http://marxan.net/downloads/uq_marxan_web_2/module5.html). The columns are:

Run_Number	The index of each solution in the object.
Status	The status of the solution. The values in this column correspond to outputs from the Gurobi software package (http://www.gurobi.com/documentation/6.5/refman/optimization_status_codes.html).
Score	The objective function for the solution.
Cost	Total cost associated with a solution
Planning_Units	Number of planning units selected in a solution
Connectivity_Total	The total amount of shared boundary length between all planning units. All solutions in the same object should have equal values for this column.
Connectivity_In	The amount of shared boundary length among planning units selected in the solution
Connectivity_Edge	The amount of exposed boundary length in the solution
Connectivity_Out	The number of shared boundary length among planning units not selected in the solution
Connectivity_Fraction	The ratio of shared boundary length in the solution (Connectivity_In) to the total amount of boundary length (Connectivity_Edge). This ratio is an indicator of solution quality. Solutions with a lower ratio will have less planning units and will be more efficient.
