Supplementary Files for "Backscoring in Principal Coordinates Analysis"
=============================================

Data and R code necessary for the reproduction of the results reported
in the paper are presented here. The code has not been written and
documented in a manner conducive to generalisation. This is merely
proof of concept. Extensive further research would be necessary to
develop efficient and robust algorithms to achieve this.

1a. handquat.rda - an R dataset containing the quaternions representing the hand orientations
1b. orient.R - R code demonstrating the computation for the orientation example.

2a. faceshapes.rda - an R dataset containing the facial shape data used in the shape example.
2b. shape.R - R code demonstrating the computation for the shape example.

3a. funcs.rda - an R dataset containing the curve data for the functional data example.
3b. fda.R - R code demonstrating the computation for the FDA example.

4. mixed.R - R code demonstrating the computation for the mixed data types example. (data example from R package)

5. funcs.R - R functions used in the four data examples.

In addition, several R packages have been used in the analysis: abind, ade4, dtw, orientlib, scatterplot3d, shapes.
