countNeighbors: Count neighbors around

In adalardo/Rppsp: R functions to manage permanent plot data (short line)

Count neighbors around

Description

Count number of neighbor for each point for a given r distance neighborhood

Usage

countNeighbors(x, y, xlim = c(0, 1), ylim = c(0, 1), r = 0.1)

Arguments

x, y	Numeric vectors with 'x' and 'y' coordinates in a cartesian space. They must have the same length.
xlim, ylim	Numeric vectors with two values defining the 'x' and 'y' axis limit in the cartesian plane.
r	dis.tance for neighborhood definition.

Value

'countNeighbors' returns a integer vector with counts the number of neighbors around each point at the maximum distance 'r'
