SkinSim

SkinSim is a Quarto-based research website for statistical modeling of human skin reflectance spectra.

The project integrates real measurements (ISSA) and simulated spectra to support:

• reproducible spectral analysis,
• biologically informed modeling (melanin and erythema effects),
• synthetic spectrum generation and validation.

Project structure

• analysis/: Quarto analysis reports (.qmd)
• notebooks/: Jupyter notebooks (.ipynb)
• code/: reusable Python and R modules/scripts
• data/: source and derived datasets
• output/: generated figures, tables, and exports
• docs/: rendered static website output

Environment setup

R environment

source("renv-setup.R")

Python environment

python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

Local development

Run the live preview server:

quarto preview

Render website

Build the full site to docs/:

quarto render

Recommended workflow

1. Add or update analysis content in analysis/ or notebooks/.
2. Keep reusable model code in code/.
3. Store intermediate and final artifacts in output/.
4. Preview frequently with quarto preview.
5. Commit both source files and rendered updates when publishing.

Notes

• The website uses Quarto navigation and supports both R and Python execution.
• Notebook pages are rendered as part of the same site output.
