%description
A tool for Hierarchical Climate Regionalization applicable to any
correlation-based clustering. It adds several features and a new
clustering method (called, 'regional' linkage) to hierarchical clustering
in R ('hclust' function in 'stats' library): data regridding, coarsening
spatial resolution, geographic masking, contiguity-constrained clustering,
data filtering by mean and/or variance thresholds, data preprocessing
(detrending, standardization, and PCA), faster correlation function with
preliminary big data support, different clustering methods, hybrid
hierarchical clustering, multivariate clustering (MVC), cluster
validation, visualization of regionalization results, and exporting region
map and mean timeseries into NetCDF-4 file. The technical details are
described in Badr et al. (2015) <doi:10.1007/s12145-015-0221-7>.
