%description
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. (2024) <doi:10.48550/arXiv.2407.12633>, 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.
