colourlog: generate plots of colourlogs from core photographs

Ilja J. Kocken

This is the R script to convert output from the DeCrack matlab script by Zeeden et al., 2015 to colour information, link it back to core depth, apply an agemodel, and create figures.

The code and explanation for the analysis is in 2022_colourlog.Rmd, which is rendered as a nice HTML file here.
