highest_concentration

`highest_concentration()` is deprecated. Use
<code>concentration_hotspot</code> for fixed-radius hotspot detection in
new analyses.

internal

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>.
