Details
On a Unix-alike, the default for zip will by default use the
value of R_ZIPCMD, which is set in etc/Renviron if an
unzip command was found during configuration. On Windows, the
default relies on a zip program (for example that from
Rtools) being in the path. The default for flags is that appropriate for zipping up a
directory tree in a portable way: see the system-specific help for the
zip command for other possibilities.
Argument extras can be used to specify -x or -i
followed by a list of filepaths to exclude or include.
