title: "Crafting Illusions: human-made composite coating used to simulate amber beads in Prehistoric Iberia"Supplementary 2---R version 4.3.2‘prospectr’ version 0.2.6‘grDevices’ version 4.3.2---Supplementary 2 is composed of 2 files containing the raw spectra 1. rawdata.csv 2. data_t.RDS 3. Band_fitting_fig5.Rmd 4. Supplementary2.docx 5. Supplementary2.jpeg 6. READMEThe .csv file can be opened with the preferred spreadsheet application.To reproduce the whole analysis you need to open Band_fitting_fig5.Rmd in R or RStudio, and setup the working directory to the folder where data_t.RDS and Band_fitting_fig5.Rmd are located.Once the working directory has been setup, just run each chunk of code of the R markdown file to reproduce the entire analysis.Figures 5.1 and 5.2 can also be reproduced by running the adequate chunks.Supplementary2.jpeg contains the individual plot of all the raw spectra. It can be reproduce by running the last chunk of the R markdown file.Supplementary2.docx file contains a comprehensive analysis of the spectra.
