isoniche: Isodar-Adjusted, Abundance-Independent Niche Breadth

Estimates habitat niche breadth corrected for the effects of abundance, using isodars (the relationships between a species' densities in pairs of habitats under density-dependent habitat selection). Fits pairwise and n-dimensional isodars, including data where sites lack some habitats, and computes the isodar-adjusted inequality (IAI) at any total abundance, with density-independent and density-dependent niche breadth, bootstrap confidence intervals and diagnostics. Method described in Granot, Dubiner and Belmaker (in revision, Ecology Letters).
