geos_nearest

geos_nearest_indexed

geos_nearest_hausdorff

geos_nearest_frechet

Finds the closest item index in <code>tree</code> to <code>geom</code>, vectorized along <code>geom</code>.

Provides an R API to the Open Source Geometry Engine
('GEOS') library (<https://libgeos.org/>) and a vector format
with which to efficiently store 'GEOS' geometries. High-performance functions
to extract information from, calculate relationships between, and
transform geometries are provided. Finally, facilities to import
and export geometry vectors to other spatial formats are provided.

geos_nearest function

<dl><dt>geom</dt>
<dd>A GEOS geometry vector</dd>
<dt>tree</dt>
<dd>A <code>geos_strtree()</code></dd>
<dt>densify</dt>
<dd>A fraction between 0 and 1 denoting the degree to which
edges should be subdivided (smaller value means more subdivisions).
Use NULL to calculate the distance as-is.</dd></dl>
