This document tabulates the state of the slides in lecture_*/slides/<chapter>/ based on

  1. compilation checks (does it compile,and if not, is there a salient error message?) and
  2. (optionally and rarely) comparison with presumably “known good” versions of the slides located in lecture_*/slides-pdf/

If you’re missing a lecture here after rendering this site interactively, you might have to add them to the included_lectures files or ensure they are downloaded correctly.

Tables are organized by lecture (first level) and lecture chapters corresponding to folders in slides/<chapter> (second level), with a table per chapter. chapters ignore certain folders like attic and all.

  • Slide: The <slide-name> with a link to the compiled .tex file (if it compiles).
  • Compiles?: Whether the .tex file compiles without error using latexmk -pdf. This can depend on the availability of specific LaTeX dependencies, but assuming they are not the issue, this usually indicates syntax issues or things like \includegraphics calls using relative paths that work on Overleaf but not locally.
  • Comparison: Checking the compiled <slide-name>.tex against slides-pdf/<slide-name>.pdf using diff-pdf-visually:
    • ❌: The check failed surely, either due to differing page counts or because there is no reference PDF.
    • ❓: The check indicates differences on at least one slide, but they may be minor and need manual checking.
    • ✅: The check seems to be fine, the PDF files match.
  • Note: A comment on the previous column listing the specific reason for a failing check. Also enumerates the slide pages where differences are found, and links to a PDF containing a diff of the two files generated with diff-pdf (at a lower resolution than the originals).

Figure Audit

After compilation, .fls recorder files capture every file the TeX engine opened. This allows robust detection of which figures each slide actually uses, including dynamically constructed paths (e.g. \foreach loops) that regex-based parsing misses.

Figures in figure/ or figure_man/ that are not referenced by any slide are orphaned. Figures referenced by slides but missing from disk are missing.

Each lecture chapter may have two figure directories:

  • figure/ — generated figures, typically produced by R scripts in rsrc/
  • figure_man/ — manually created or externally sourced figures, not generated by scripts

Figures are counted separately per figure/ and figure_man/ folders:

  • Total means all figures in the respective folder
  • Orphaned figures are in the folder but not used by any .tex file in the chapter
  • Missing figures are referenced in .tex files but not in folder (will cause LaTeX compilation error anyway)
  • Attic counts figures in an attic subfolder which might need to be cleaned out
