cospect {tsvr}

Calculate the cospectrum between all pairs of time series

Description

This function is used to calculate the cospectra between pairs of time series, including each time series with itself. These are based on simple ffts without smoothing.

Usage

cospect(X)

Arguments

X

a matrix with counts or densities arranged in species by time step.

Value

cospect return a list with elements

frequency

a vector from 0 to 1 of the frequencies used

cospectrum

a 3D array, with cospectrum range in species by species by frequency
