Error in lintr GitHub action

[AQLT]

I understand that it comes from the fact that the GA uses ubuntu and utils::choose.files only exists in Windows

Ok, so first of all, the linter issue can be ignored with an added item in the .lintr file.
In the long run, we can add a # nolint tag to the problematic line or create an exclusion in the .lintr file.

If the issue can be ignored then we should removed the error from the GitHub action for pull request. It can be disturbing to see that every PR failed: in my opinion, the checks in PR should prevent from error in the code and not create false alarm with checks which can be ignored.
