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. Since
extras will be treated as if passed to system, if
the filepaths contain spaces they must be quoted e.g. by
shQuote.
The status value returned by the external command, invisibly.
unzip, unz; further, tar and
untar for (un)packing tar archives.
