No link checking at all; both sibling templates run check-links

[d-morrison]

This repo has no link checking in any of its 14 workflows — no lychee, no check-links, nothing. Both sibling templates do:

Repo	Link checking
qwt	d-morrison/gha/.github/workflows/check-links.yml@v2
qbt	d-morrison/gha/.github/workflows/check-links.yml@v2
rpt	none

That matters more here than in a book template, because an R package template ships documentation full of links that rot in exactly the ways a checker catches: @seealso and @references URLs in roxygen blocks, badge URLs in README.Rmd, DESCRIPTION's URL/BugReports fields, vignette citations, and the altdoc site's own cross-references. None of R CMD check, lintr, or the spellcheck looks at any of them.

Since this is a template, every package created from it inherits the gap.

Suggested fix

Add a caller stub for the shared workflow, matching what qwt/qbt already do:

# .github/workflows/check-links.yml
name: Links
on:
  pull_request:
  push:
    branches: [main]
  schedule:
    - cron: "0 0 * * 0"   # weekly, catches rot with no code change
jobs:
  link-checker:
    uses: d-morrison/gha/.github/workflows/check-links.yml@v2
    permissions:
      contents: read
      issues: write        # files an issue when a scheduled run on main fails

Copy the exact shape from gha/examples/check-links.yml rather than the above, which is from memory of the sibling stubs.

Two things worth carrying over from qwt/qbt while doing it:

• a lychee.toml at the repo root (this repo has none) — needed to exclude template-placeholder URLs, which would otherwise fail on day one for every package generated from the template
• the links checked by hand skip label, so a PR that knowingly adds a not-yet-live URL can opt out

The weekly cron is the part that earns its keep: link rot happens with no commit to trigger a PR run.

Found while auditing all three templates' CI against IndrajeetPatil/workflows; rpt is by far the least migrated of the three (1 of 14 workflows calls gha, versus 3 of 12 in qwt and 6 of 11 in qbt), so there may be more gaps of this kind worth a separate pass.

[github-actions]

The GitHub issue highlights the lack of link-checking workflows in the rpt repository template, unlike its sibling templates, qwt and qbt, which use a shared workflow for checking links. The absence of link-checking is particularly problematic for an R package template, as it includes numerous potentially broken or outdated links in documentation, metadata, and other areas. The proposed fix is to add a workflow for link-checking, leveraging the shared workflow used by the other templates, and supplement it with a lychee.toml file to exclude placeholder URLs and a "links checked by hand" label to handle exceptions. A weekly cron schedule is recommended to proactively detect link rot. This issue was identified during a broader CI audit of related templates, suggesting more migration gaps might exist.
