[R-pkg-devel] Question about notes

[João Pedro de Almeida dos Santos]

I'm checking a package in RHub via RStudio (devtools::check_rhub()) and I'm receiving the following note:

checking for non-standard things in the check directory ... NOTE
  Found the following files/directories:
    ''NULL''

  I am unable to find this NULL file/directory anywhere, even with the ls() command in RStudio. I even deleted my local repo and re-cloned it, but this note persists.

What can I do to solve this?

Thanks in advance,
Jo�o Santos.
