knnIndep (version 2.0)

generate.paths: Generate all nearest neighbours distances for one point in a sample

Description

Help function which generates the nearest neighbhour distances for a single point in a sample, assuming rank data on a torus with the maximum distance.

Usage

generate.paths(index, rx, ry, N)

Arguments

index

for which point to calculate the nearest neighbhour distances

rx

ranked data (1st dimension)

ry

ranked data (2nd dimension)

N

Number of points in sample

Value

a vector of length (N-1) containing the sorted distances to the nearest neighbour of point index in the sample

Examples

    x=rank(runif(10))
    y=rank(runif(10))
    knnIndep:::generate.paths(5,x,y,10)
    #for all points in the sample
    sapply(1:10,knnIndep:::generate.paths,x,y,10)
