Polish is quantitatively different on quartzite flakes used on different worked materials [R analysis]

This upload includes the following files related to the R analysis:

- Raw data as a CSV table (processing-quartzite-final.csv), i.e. results from the ConfoMap analysis (see https://doi.org/10.5281/zenodo.3979116)

- RStudio project (Quantification quartzite final.Rproj)

- R scripts as R Markdown files (*.Rmd)

- R scripts knitted to HTML files (*.html)

- An R script (RStudioVersion.R) to write the used version of RStudio to a text file (RStudioVersion.txt)

- Output from script #1: processing-quartzite-final.Rbin and processing-quartzite-final.xlsx

- Output from script #2: processing-quartzite-final_summary-stats.xlsx

- Output from script #3: all plots as PDF files.

Note that for running the scripts, the raw data files (processing-quartzite-final.csv, .Rbin and .xlsx) should be stored in a "Data" folder within the working directory.
Output (processing-quartzite-final_summary-stats.xlsx and PDF plots) were saved into "Summary-stats" and "Plots" folders, respectively.

Zenodo does not allow sub-folders, so this folder structure had to be removed.

Instructions to download all files at once are given here: https://doi.org/10.5281/zenodo.4011952
