On a Unix-alike, the default for zip
will use the
value of R_ZIPCMD, whose default is set in ‘etc/Renviron’
to the zip
command 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.
