CRAN 拒绝基于“描述包中方法的参考”

Question

I received this cryptic CRAN message:

Thanks,

If there are references describing the methods in your package, please add these in the description field of your DESCRIPTION file in the form authors (year) doi:... authors (year) arXiv:... authors (year, ISBN:...) or if those are not available: https:... with no space after 'doi:', 'arXiv:', 'https:' and angle brackets for auto-linking.

Please fix and resubmit, and document what was changed in the submission comments.

I don't get it, the DESCRIPTION file seems quite standard, here it is:

Package: inops
Title: Infix Operators for Detection, Subsetting and Replacement
Version: 0.0.1

    person("Antoine", "Fabri", email = "***@gmail.com", role = c("aut", "cre")),

    )
Description: Infix operators to detect, subset, and replace the elements matched by a given condition.
  The functions have several variants of operator types, including subsets, ranges, regular expressions and others.
  Implemented operators work on vectors, matrices, and lists.

Seems related to bullet points 5 to 7 but I don't see how it's relevant here: https://cran.r-project.org/web/packages/submission_checklist.html

Any idea what's expected from me here?

The repo if it helps: https://github.com/moodymudskipper/inops

If you are using RStudio to create your package, can you follow this checking? http://r-pkgs.had.co.nz/check.html

devtools::check()

And follow the prompt, it might help you find the problem.
