HespDiv

hespdiv is an R package implementing the HespDiv framework for hierarchical spatial data subdivision. The package provides tools for identifying topologically contiguous spatial clusters and analysing hierarchical regionalization structures in palaeobiogeography and related spatial datasets.

HespDiv represents a suitable framework for identifying hierarchically nested, spatially contiguous regions (geobiomes sensu Spiridonov & Eldredge (2024)) from taxonomic occurrence data.

The theoretical foundations of HespDiv are laid out in my PhD dissertation (link to be added!) and in:

Daumantas, L. & Spiridonov, A. (2024). hespdiv: an R package for spatially constrained, hierarchical and contiguous regionalization in palaeobiogeography. Palaeontology, 67(3), e12702. https://doi.org/10.1111/pala.12702

Installation

You can install the development version from GitHub: {r eval = FALSE} if (!require("devtools")) install.packages("devtools") devtools::install_github("Liudas-Dau/hespdiv") # Example and walkthrough A full demonstration of the workflow is provided in the vignette:

“HespDiv Walkthrough: Case of US Miocene Mammals”

The vignette illustrates how to:

prepare spatial occurrence data
perform hierarchical spatial subdivision
analyse subdivision results
visualise hierarchical regionalization patterns

Example datasets

The walkthrough uses example datasets distributed in a separate package:

{r eval = FALSE} # install devtools is you don't have it! devtools::install_github("Liudas-Dau/hespdiv_data")
