sum_dist: Sample Distance

In heike/rotations: Tools for working with rotational data

Description

Compute the sum of the pth order distances between Rs and S

Usage

  sum_dist(Rs, S = genR(0, space = class(Rs)),
    method = "projected", p = 1)

  ## S3 method for class 'SO3'
 sum_dist(Rs, S = id.SO3,
    method = "projected", p = 1)

  ## S3 method for class 'Q4'
 sum_dist(Qs, S = id.Q4,
    method = "projected", p = 1)

Arguments

Rs	a matrix of rotation observations, one row per observation
S	the individual matrix of interest, usually an estimate of the mean
method	type of distance used method in 'projected' or 'intrinsic'
p	the order of the distances to compute

Value

the sum of the pth order distance between each sample in Rs and S

NULL

NULL

Examples

r<-rvmises(20,0.01)
Rs<-genR(r)
Sp<-mean(Rs)
sum_dist(Rs,S=Sp,p=2)
