In LKremer/ggpointdensity: A Cross Between a 2D Density Plot and a Scatter Plot

Count Neighbors within a Radius

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.
