Balanced variation and abundance gradient components for abundance data
bray_curtis_balanced(x, y)bray_curtis_gradient(x, y)
ruzicka_balanced(x, y)
ruzicka_gradient(x, y)
Numeric vectors
The balanced variation or abundance gradient component of distance
between x and y. This quantity is undefined when either
x or y have all elements equal to zero, in which case we
return NaN.
