par_make_balanced: Generate groups based on balanced clustering

In chopin: Spatial Parallel Computing by Hierarchical Data Partitioning

Generate groups based on balanced clustering

Description

For balancing computational loads, the function uses the anticlust package to cluster the input points. The number of clusters is determined by the num_cluster argument. Each cluster will have equal number of points. Grids will be generated based on the cluster extents. At the lower level, the function uses terra::distance() function to calculate the Euclidean distance between points.

Usage

par_make_balanced(points_in = NULL, n_clusters = NULL)

Arguments

points_in	sf or SpatVector object. Target points of computation.
n_clusters	integer(1). The number of clusters.

Value

SpatVector object with a field "CGRIDID".

Note

This function is only for two-dimensional points. The results will be irregular grids with or without overlapping parts.
