nndist.s2pp: Nearest Neighbour Distance for Points on Sphere

In spatstat/spatstat.sphere: Point patterns on the Sphere

Nearest Neighbour Distance for Points on Sphere

Description

Nearest Neighbour Distance for Points on Sphere

Usage

## S3 method for class 's2pp'
nndist(X, ..., k = 1, chordal = FALSE)

Arguments

X	Point pattern on the sphere of class "s2pp".
...	Further arguments passed to [spatstat.geom::nndist.pp3()]. Only the argument by can be used by this function.
k	Positive integer to calculate the kth nearest neighbour.
chordal	logical. Cordal distance cutting through the earth if TRUE. Otherwise, distance along the surface of the sphere if FALSE.

Value

Numeric vector (if length(k)=1) or matrix (if length(k)>1) of distances. If the additional argument by is used this may be a data.frame.
