Data & R Script for “Blurred Boundaries: Exploring the Complexity of the Production System at the Luomaqiao Kiln in Yuan-Dynasty Jingdezhen”

This deposit provides all raw and supplementary geochemical datasets (LA‑ICP‑MS measurements of ceramic paste and glaze) and the master R script (run_all.R) used to reproduce the analyses in Xu et al. (2025), “Blurred Boundaries: Exploring the Complexity of the Production System at the Luomaqiao Kiln in Yuan‑Dynasty Jingdezhen.” Journal of Archaeological Science. https://doi.org/10.1016/j.jas.2025.106328

Contents:

data/raw/

Dataset_S1.csv: LA‑ICP‑MS elemental concentrations of ceramic paste

Dataset_S2.csv: LA‑ICP‑MS elemental concentrations of ceramic glaze

data/supplementary/

Dataset_S3.csv: Catalogue of porcelain samples

Dataset_S4.csv: Mahalanobis‑based group membership probabilities for paste samples

Dataset_S5.csv: Mean, SD, and RSD of elemental concentrations by claw category

run_all.R: Master R script (installs dependencies, processes data, runs HCA/PCA, and generates Figures 4–13 and Tables 1–2)

README.md: Project overview, file map, usage instructions, and software environment

Reproducibility & Requirements:

R ≥ 4.4.0 (download at https://cran.r-project.org/)

CRAN packages: here, dplyr, tidyr, ggplot2, dendextend, tibble, factoextra, ggrepel, ggpubr, stringr

Running run_all.R will install all required packages, regenerate all manuscript figures and tables, and write a session_info.txt file into results/ for full provenance.
