Takes a matrix of abundance or biomass data and returns the synchrony index. The synchrony index varies between 0 (maximally asynchronous) and 1 (maximally synchronous) and is independent of the number of species or subpopulations.
1 | synchrony(x)

x |
A matrix or dataframe of abundance or biomass data. The columns should represent different subpopulations or species. The rows should represent the values through time. |
