Find the mean distance to nearest neighbor for a collection of Cartesian coordinates

Description

Given a data frame containing X and Y Cartesian coordinates, find the arithmetic and geometric mean distance to the nearest point.

Usage

NN_mean(dataframe, x_var, y_var)

Arguments

dataframe	A data frame. Must contain numeric variables corresponding to x_var and y_var containing the X and Y coordinate values.
x_var	Character string. The name of the variable in dataframe containing the X components of the coordinates.
y_var	Character string. The name of the variable in dataframe containing the Y components of the coordinates.

Value

A named numeric vector of the mean distances: "arith_mean" containing the arithmetic mean and "geo_mean" containing the geometric mean.
