Overview

About

Maintained by Erick A. Chacón-MontalvánCRAN page ↗GitHub ↗Website ↗Issues ↗

Bayesian clustering of spatial regions with similar functional shapes using spanning trees and latent Gaussian models. The method enforces spatial contiguity within clusters and supports a wide range of latent Gaussian models, including non-Gaussian likelihoods, via the R-INLA framework. The algorithm is based on Zhong, R., Chacón-Montalván, E. A., and Moraga, P. (2026) doi:10.1002/sim.70597, extending the approach of Zhang, B., Sang, H., Luo, Z. T., and Huang, H. (2023) doi:10.1214/22-AOAS1643. The package includes tools for model fitting, convergence diagnostics, visualization, and summarization of clustering results.

Changes in 1.1.1

Documentation fixes

Rewrote the "Advanced features" vignette (vg02-advanced-features.Rmd) to use nclust directly instead of an explicit genclust() call, and to demonstrate the path_save/nsave checkpointing arguments; regenerated the corresponding cached vignette data (gaussian-mcmc1.rds, gaussian-mcmc2.rds).
Fixed the "Standardized daily temperature at Canadian stations" vignette (vg12-temp-canada.Rmd): added sort = TRUE to plot_clusters_series() so its cluster numbering matches plot_clusters_map()/plot_clusters_fitted(), and corrected the resulting narrative description of cluster shapes.

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("sfclust", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("ErickChacon/sfclust")

Development version from ErickChacon/sfclust. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-sfclust

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-sfclust

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-sfclust

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
