k.nearest.angles: Get angle from each point to its k nearest neighbours

In ClairBee/AS.angles: ArchStats: extracting angles from x,y coordinates

Description

For each point in the set, uses knnx.index to obtain the k nearest neighbours, then applies atan2 to get the angle between them.

Usage

k.nearest.angles(pts, k)

Arguments

pts	A two-column matrix containing the coordinates of the points to be compared.
k	Number of neighbours to be included for each point.

Value

A (k+2)-column matrix; the first two columns contain each point's x and y coordinates, the remainder containing the angles found

Examples

k.2 <- k.nearest.angles(p, 2)
