How to test:

Download and unpack the artefacts from the latest pages job (e.g.), then run:

library(xml2)
list.files('public', full.names=TRUE, recursive=TRUE, pattern = '\\.html$', ignore.case=TRUE) |>
	setNames(nm = _) |> lapply(read_html) |> lapply(\(x) c(
		x |> xml_find_all('//img|//script') |> vapply(xml_attr, '', 'src'),
		x |> xml_find_all('//a') |> vapply(xml_attr, '', 'href')
	)) |> (\(L) Map(\(links, path)
		links[
			!is.na(links) &
			!startsWith(links, 'mailto:') &
			!startsWith(links, 'data:') &
			!startsWith(links, 'https:') &
			!startsWith(links, 'http:') &
			!file.exists(file.path(dirname(path), sub('#.*', '', links)))
		],
	L, names(L)))() -> missing

They can be split into a few classes:

• General:
  • public/GOVERNANCE.html → .github/CODE_OF_CONDUCT.md
  • public/reference/notin.html → ../../help/chmatch.html (why this one?)
• Links from litedown man pages to vignettes
  • e.g. public/reference/assign.html → ../../doc/datatable-reference-semantics.html
  • should be solvable with a symlink
• Links from litedown man pages to 00Index.html, once on every page
  • e.g. public/reference/as.xts.data.table.html → ../00Index.html
  • can be removed in bulk
• Links from "classic" help pages into other parts of the library, many of those
  • e.g. public/library/data.table/html/substitute2.html → ../../base/help/substitute.html
• Links from rendered NEWS to parts of the R help system:
  • e.g. public/doc/html/NEWS.html → ../help/figures/../../html/Rlogo.svg, repeats many times
• Links to various parts of the R help system, from pages that are possibly not intended to be visited(?), e.g.,
  • public/articles/index.html → /doc/html/Rlogo.svg (many broken links from there)
  • public/doc/html/index.html → ../manual/R-intro.html
  • public/doc/html/SearchOn.html → /doc/html/hsearch_db_concepts.html
