Historical Biogeography focuses basically on sympatry patterns among species. SyNet extracts hypotheses of sympatry from available distributional evidence and integrates them into weighted and binary sympatry networks. SyNet tests the adequacy of networks to be segregated into groups of species cohesively sympatric (units of co-occurrence). It identifies units of co-occurrence from the more inclusive network where they are embedded. NAM algorithm iteratively removes intermediary species that are linked to those units otherwise disconnected. Here, you can do among other things: i) to analyze the spatial affinity between sets of records and ii) to explore dynamically the cleavogram associated to the analysis of sympatry networks. You can track many new ideas on numerical classification throughout the examples of functions. Remarkably, geographical data associated to any network partitioning can be exported to KML files which can be opened via Google Earth.

reweight
(Package: SyNet) :
Reweighting of Links from an Adjacency Weighted Matrix
Transforms a weighted matrix into another one constrained into a common scale of relative strength. Values are reweighted by a combination of rewards and punishments. For a given link, its relative strength increases with the number of triads where it is the strongest and decreases with the number of triads where it is the weakest.
