SpecPP

An R package for spectral analysis of multivariate spatial point patterns in a rectangular region (Ding et al., 2025). Given a multivariate point pattern and a parametric model of the intensity function, this package facilitates the characterization of frequency-domain features from your data through kernel smoothing. It includes functions for spectral density estimation, bandwidth selection, visualization, and coherence analysis.

Installation

You can install the development version of SpecPP from GitHub with:

# install.packages("pak")
pak::pak("qwding101/SpecPP")

Tutorial

This tutorial demonstrates how to use SpecPP to analyze multivariate point pattern data.
