classic_partition {partitionBEFsp}

Calculate classic partition

Description

calculates the classic selection and complementarity effects, sensu Loreau and Hector 2001

Usage

classic_partition(DRY, M, N = length(M), Q = N,
  uncorrected_cov = FALSE)

Arguments

DRY

change in relative yield, as calculated by the calculate_DRY function

M

monoculture biomass

N

number of species in the sample - defaults to length(M)

Q

number of species in the full population - defaults to N - only required if uncorrected_cov="COMP"

uncorrected_cov

A character, which can be TRUE, FALSE, or COMP. Tells whether to use the standard sample-size corrected covariance function (FALSE), or a covariance function that is not corrected for sample size (TRUE), or a "compromise" function that resembles the standard function for N < Q, and that resembles the non-corrected function for N ~ Q If TRUE, then SS + CS = YO - YE, sensu Loreau and Hector 2001 defaults to FALSE note - we do not recommend setting this to TRUE or "COMP", unless you require SS+CS=YO-YE

Value

a list with elements S (the selection effect) and C (the complementarity effect)
