Nestedness and turnover components for presence/absence data
jaccard_turnover(x, y)jaccard_nestedness(x, y)
sorenson_turnover(x, y)
sorenson_nestedness(x, y)
Numeric vectors
The nestedness or turnover component of distance between x
and y. This quantity is undefined when either x or y
have no observations, in which case we return NaN.
