Those files would both be invisible when using the Finder.app unless you used ls in a terminal session, but I guess you figured that out

In 2008 it was reported in the NEWS for R 2.7.1 that:


o R CMD build tries harder to clean up the inst/doc directory from the remnants of earlier builds.

It also removes any directories with extension .Rcheck, and files .DS_Store and ._* (created by tar on Mac OS X under some circumstances: it now sets environment variables to ask for such files not to be created by that tar.)

So we need to ask if this was just a warning message. It appears that there are mechanisms in place to remove those files.

(It's arguably an R-devel topic.)
