bw_ref

A simple wrapper for the MASS::bandwidth.nrd function. Divides values by 4 to match the scale of ks methods

Applies methods used to estimate animal homerange, but
instead of geospatial coordinates, we use isotopic coordinates. The estimation
methods include: 1) 2-dimensional bivariate normal kernel utilization density
estimator, 2) bivariate normal ellipse estimator, and 3) minimum convex polygon
estimator, all applied to stable isotope data. Additionally, functions to
determine niche area, polygon overlap between groups and levels (confidence
contours) and plotting capabilities.
