Description
Takes bivariate isotope data in x and y with a grouping variable and returns
a list that contains the posterior distribution of the 6 niche width
metrics for application to community type data
described by Layman, C.A., Arrington, D.A., Montana, C.G., & Post, D.M.
(2007) Can stable isotope ratios provide for community-wide measures
of trophic structure? Ecology, 88, 42-48.
Usage

Arguments
X
Data for the x-axis.
Y
Data for the y-axis.
G
A grouping variable
R
The number of posterior draws to make
Value
metrics
A Rx6 matrix containing the R posterior draws in rows, and the
metrics in columns in the order: dNr, dCr, TA, CD, MNND, SDNND.
