Spatially-aware Self-Organizing Maps(GeoSOM) model

Implementation of spatially-aware self-Organizing maps(GeoSOM) model model based on kohonen::supersom().

Usage

geosom(data, coords, wt, grid, normalize = TRUE, ...)

data: A data.frame or tibble
coords: The coordinate column name in the data.
wt: The weight of spatial coordination and the weight of the non-spatial attribute is 1. If wt is 0,now it equal to som model.
grid: A grid for the codebook vectors: see geosomgrid.
normalize: (optional)Boolean, indicating whether non-spatial feature data should be normal standardization,default is True.
...: Other arguments passed to kohonen::supersom(),see ?kohonen::supersom().

An object of class "kohonen" with components.
