In Hmsc: Hierarchical Model of Species Communities

Simulated data and a fitted Hmsc model for a small species community.

Description

This dataset contains simulated occurence data for 4 species in 50 sampling units. The data is based on a hierarchical study design consisting of 50 sampling units in 10 georeferenced plots. Occurences of 4 species were simulated using one continuous environmental variable (x1) and spatial autocorrelation between the plots. Response of species to the environment are related to one species trait which is fully phylogenetically structured. This dataset is used for the examples and package testing. The variables are as follows:
