[R-SIG-Mac] Does R CMD check create invisible files?

[Kasper Daniel Hansen]

I am using a mac and I have never seen these files.  My best bet is that it
is hidden files from your text editor, and that - for example -
._DESCRIPTION is an autosave of DESCRIPTION.  Emacs does that, but would
name it DESCRIPTION~.  So I would like into your editor.  R removes certain
files automatically (like the Emacs autosave) when it runs R CMD build, but
it seems you need to start using .Rbuildignore.

Best,
Kasper
