Create a spacemodel object

spacemodel.Rd

Constructor for the `spacemodel` class. This function combines spatial data (a raster stack) and ecological data (a trophic table) into a single object used for modelling.

Usage

spacemodel(raster_stack, trophic_tbl)

Arguments

raster_stack

A SpatRaster object (multi-layer stack) representing the spatial distribution of the species or groups.

trophic_tbl

An object of class trophic_tbl containing the ecological parameters and properties of the species.

Value

A SpatRaster object with the following additional attributes:

  • trophic_tbl: The trophic_tbl object passed as input.

  • spacemodel: A logical flag set to TRUE, indicating this raster is part of a spacemodel.

Details

The function performs several checks to ensure data consistency:

  • Verifies that raster_stack is a SpatRaster.

  • Verifies that trophic_tbl is a trophic_tbl object.

  • Ensures the number of raster layers matches the number of levels in the trophic table.

  • Ensures that the names of the raster layers match the names in the trophic table.
