cv2f: Compute a frequency-specific version of CVcom or CVcomip

In tsvr: Timescale-Specific Variance Ratio for Use in Community Ecology

Description

Compute a frequency-specific version of CVcom or CVcomip.

Usage

cv2f(X, type)

Arguments

X	A matrix with counts or densities arranged in species by time step
type	If com, calculate a frequency-specific CVcom2. If comip, calculate a frequency-specific CVcomip2. See the vignette for definitions of these quantities.

Value

cv2f returns an object of type list consisting of

frequency	a vector from 0 to 1 (not including 0 and 1)
cv2	A vector of frequency-specific population or community variability
