Dear all,
On my Mac running Yosemite I zip my package:
$ tar czf xps_1.35.1.tar.gz xps
The directoy 'xps' does not contain any hidden files!
However, when I run:
$ R CMD check xps_1.35.1.tar.gz
I get:
...
* checking for hidden files and directories ... NOTE
Found the following hidden files and directories:
.BBSoptions
._.BBSoptions
._ACKNOWLEDGMENT
._DESCRIPTION
...
etc
When I unzip my package using:
$ tar xvfz xps_1.35.1.tar.gz xps
there are still no hidden files!
However, the src directory created by R CMD check, i.e.
CS-iMac:CRAN cstrato$ cd xps.Rcheck/00_pkg_src/xps/
CS-iMac:xps cstrato$ ls -al
total 504
drwxr-xr-x 40 cstrato staff 1360 Dec 16 10:30 .
drwxr-xr-x4 cstrato staff136 Dec 16 10:29 ..
-rw-r--r--1 cstrato staff 26 Sep 30 23:33 .BBSoptions
-rw-r--r--1 cstrato staff181 Sep 30 23:33 ._.BBSoptions

-rw-r--r--1 cstrato staff181 Dec 16 10:20 ._DESCRIPTION
-rw-r--r--1 cstrato staff181 Dec 16 10:26 ._NAMESPACE
does indeed contain hidden files from all my files!
Can anybody explain this behavior and tell me how to avoid this behavior?
Those are fork files: the OS X tar differs from POSIX by treating Apple
forks in a non-POSIX-standard way, and *by default* R CMD check does not
use the OS's tar command (as ?check explains).
Do read and follow the documentation: use R CMD build not your OS's tar
to 'zip' (your incorrect terminology) a package. (Or read the source
code for tar() and note that it sets various environment variables on OS X.)
fortunes::fortune(14) really does apply.
