Dear maintainer,

Please see the problems shown on
https://cran.r-project.org/web/checks/check_results_oxcAAR.html.

Please correct before 2021-07-12 to safely retain your package on CRAN.

It seems we need to remind you of the CRAN policy:

'Packages which use Internet resources should fail gracefully with an informative message
if the resource is not available or has changed (and not give a check warning nor error).'

This needs correction whether or not the resource recovers.

The CRAN Team

[MartinHinz]

implemented desired behavior in Branch quickfix_download_and_cran_checks with 1ee51c2 and 3cd31e0. Next steps: CRAN re-release: suggested name: Karpo.

[MartinHinz]

Remerge into master is requested after review.

After that: Check for release/resubmit:

• The package works and all functions are usable
• The package documentation is up-to-date and represents the functions correctly
• The test coverage of the package functions is sufficient
• DESCRIPTION is up-to-date with the latest version number and database list
• README.md is up-to-date
• NEWS.md is up-to-date and includes the latest changes
• Package checks ran and did not yield any ERRORS, WARNINGS or NOTES (or at least the NOTES are addressed in the cran-comments.md)
  • locally (devtools::check())
  • rhub (devtools::check_rhub(email = ...))
  • winbuilder (devtools::check_win_release(email = ....) + devtools::check_win_devel(email = ....))
• Spellcheck with devtools::spell_check() ran and did yield not only false-positives
• codemeta.json is up-to-date (can be updated with codemetar::write_codemeta())
• inst/CITATION is up-to-date
• The package does not make external changes without explicit user permission. It does not write to the file system, change options, install packages, quit R, send information over the internet, open external software, etc.
• No reverse dependencies break because of the new package version (devtools::revdep_check())
