cells_above_threshold

Generate a data.frame containing the cell indices of the focal
cells surpassing the specified threshold. Additionally, include columns for
the coordinates (xy) corresponding to the center of each cell.

Provides methods for spatial concentration and radius-based risk
calculations. The package focuses on efficient determination of the sum of
observations within a given radius, identifying local concentration
hotspots, and aggregating point data to polygon geometries. These methods
are useful for applications such as insurance, urban analytics,
environmental exposure analysis, and other spatial point pattern workflows.
The underlying maximum covering problem is described by Church (1974)
<doi:10.1007/BF01942293>.
