Seeds and builds Voronoi, Delaunay, hexagonal and\nsquare tessellations with reproducible identifiers, selects a\ncell count from the spatial structure of the observations,\nassigns features to cells, and aggregates to cell level with\noptional design-effect corrections so that standard errors\naccount for within-cell autocorrelation. Also manages\ncoordinate reference systems. Fits geographically weighted\nregression (via 'GWmodel'; Lu et al. (2014)\n), Bayesian spatial Gaussian\nprocess regression (via 'brms', using the Hilbert space\napproximation of Riutort-Mayol et al. (2023)\n) and random forests (via\n'ranger', with the permutation importance of Strobl et al.\n(2007) ), each behind one S3 class\nwith consistent predict, fitted, residuals and plot methods.\nProvides spatial cross-validation with random, block, buffered,\nleave-location-out and nearest-neighbour distance-matched folds\n(Mila et al. (2022) ), forward\nvariable selection, model comparison, prediction onto a regular\nsurface, and the area of applicability of Meyer and Pebesma\n(2021) to flag where a fitted\nmodel extrapolates
