IASDT.R supports the invasive alien species (IAS) Digital Twin (IASDT), as part of the EU-funded BioDT project. This R package provides functions for processing input data (biotic and abiotic) and modelling the distribution of naturalised alien plant species (NAPS) across Europe using joint species distribution models.

• More information on the BioDT project can be found at this link.
• For an overview on the IASDT, see Khan, El-Gabbas, et al. .
• Documentation of the package functions can be found here.
• Click here for the workflow of the IASDT.
• The package also depends on ecokit for general ecological data analysis and visualisation.
