In gllvm: Generalized Linear Latent Variable Models

Functions to extract ecological quantities of the latent variables from a GLLVM, if species are a quadratic function of the latent variables.

Description

Extracts species optima and tolerances, potentially with standard errors (derived with the Delta method).

Usage

## S3 method for class 'gllvm'
optima(object, sd.errors = TRUE, ...)

## S3 method for class 'gllvm'
tolerances(object, sd.errors = TRUE, ...)

Arguments

object	an object of class 'gllvm'.
sd.errors	logical. If TRUE, also returns standard errors.
...	Not used.

Details

Currently no separate method for calculating species maxima or gradient length are implemented. Gradient length can be inferred from the standard deviation of the latent variables, which is reported by summary.gllvm.
