vreq: Creator function for the vreq S3 class

Description

The vreq (variance ratio equation) class is for storing equations based on a variance ratio, as in Wang S. & Loreau M. (2016) Biodiversity and ecosystem stability across scales in metacommunities, Ecol Lett, 19, 510-518. This is a general class from which other classes inherit (vreq_classic, vreq_LdM). vreq inherits from the list class.

Usage

vreq(com, comnull, vr)

Arguments

com

comnull

com

a single positive number equal to comnull*vr

comnull

a single positive number

vr

a single positive number
