Estimates network indices, including trophic structure of foodwebs

Description

Given a network (e.g. a food web), estimates several network indices.

These include:

  • ascendency network indices,

  • direct and indirect dependencies,

  • effective measures,

  • environ network indices,

  • general network indices,

  • pathway analysis,

  • network uncertainty indices and constraint efficiencies

  • the trophic level and omnivory indices of food webs.
