Description

This function counts the number of neighboring points within a specified radius for each point in a given set of coordinates using a C implementation.

Usage

count_neighbors(x, y, r2, xy)

Arguments

x

A numeric vector of x-coordinates of the points.

y

A numeric vector of y-coordinates of the points.

r2

A numeric value representing the squared radius within which to search for neighboring points.

xy

A numeric value representing the aspect ratio (usually the ratio of the y-scale to the x-scale).

Value

A numeric vector where each element represents the count of neighboring points within the specified radius for each point.
