Introduction
The supplement contains:
a list of all script and data files used in the study; these files are supplied separately through https://datastore.landcareresearch.co.nz/dataset/jgr-soilformingfactors;
all supplementary figures referenced in the main text.
Additional files supplied separately
BanksP_chemistry.R
R code for Figure 2 using the data in ‘BanksP_lab_paper.xlsx’
BanksP_mixing.R
R code for performing Bayesian mixing model using the following input files: ‘mixdata_reduced.csv’, ‘pm_reduced_means.csv’, ‘discr.csv’; analysis produces output files ‘diagnostics.txt’, ‘summary_statistics.txt’, ‘BP_model_1.txt’ that were summarized to create ‘mixing_results.xlsx’;
Data from ‘mixing_results.xlsx’ and ‘BanksP_lab_paper.xlsx’ was used to create Figure 4 and 5
BanksP_FTIR.R
R code for statistical analysis of FTIR based on FTIR data in ‘MIR_Banks_spectra_abs_ID.csv’; used to create Figure 3
BanksP_pm.R
R code for visualizing parent material and immobile element data in Figure S1 and S3, using data from ‘BanksP_lab_paper.xlsx’ and ‘pm_paper.xlsx’
BanksP_var.R
R code for variation partitioning using ‘MIR_Banks_spectra_abs_ID.csv’, ‘mixing_results.xlsx’ and ‘BanksP_lab_paper.xlsx’ as input data; output of analysis is used for Figure S2
