Dear all,

When running R CMD check on my Mac (Yosemite 10.10.5) I get suddenly NOTEs and WARNINGs
that my tar.gz file does contain hidden files.

However, when checking the corresponding directories with 'ls -al' (or with mc)
none of these files does exist!! (with exception .BBSoptions).

Here is a partial output of 00check.log:

* using log directory '/Volumes/LumiData/CRAN/xps.Rcheck'

Does anyone know why these files are listed?
For some reason all these hidden files start with '._'

My suspicion was that maybe there is something wrong with Spotlight (i.e. mdutil) so I excluded the whole volume from Spotlight. This did not help. Adding the volume
again and thus forcing a rebuild for Spotlight did not help either.

What could I do to remove these apparently non-existing hidden files?

Best regards
Christian
