The DATA directory is a symlink to data used in the analysis. The "original" sub-folder is a read-only directory, and R should never write files here. Put processed datasets in "Working" and "Final" sub-folders as appropriate.
The SRC directory contains source code.
The OUTPUT directory contains simuation output, logs, and other interim products.
The DOC directory contains any report-type output. Markdown, LaTeX, Notebooks, etc. files go here.
The FIGS directory contains generated figures.
