In ibartomeus/traitmatch: Package to predict trait matching from species interactions

Description

This models are described in Bartomeus et al. 2016 (Functional Ecology) and are based on Williams et al. 2000 models. They are intended to be used with fit_it function. The integrated model considers both neutral and niche constraints, while the neutral and niche models only consider its respective components.

Usage

integrated_model(pars, Tlevel1, Tlevel2, mean_Tlevel1, sd_Tlevel1)

Arguments

pars	parameters obtained from fit_it function or a vector of the form c(a0 = 0, a1 = 0, b0 = 0, b1 = 0) with known parameters.
Tlevel1	Vector of trait values of the first interaction partner.
Tlevel2	Vector of trait values of the second interaction partner.
mean_Tlevel1	Mean of trait values of the first interaction partner. Can be weighted or not, and can use independent information on the trait distribution to be calculated.
sd_Tlevel1	Standard deviation of trait values of the first interaction partner. Can be weighted or not, and can use independent information on the trait distribution to be calculated.
