%description
Provides computational building blocks for fixed-radius spatial
aggregation, weighted circle-placement problems, hotspot detection, and
polygon-based spatial summaries. The package focuses on efficient
determination of the sum of observations within a given radius,
identifying areas of high local concentration, 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 fixed-radius circle placement problem
is discussed by Chazelle and Lee (1986) <doi:10.1007/BF02238188>, and
related maximum covering problems are described by Church (1974)
<doi:10.1007/BF01942293>.
