zip
Create Zip archives
A wrapper for an external zip
command to create zip archives.
Usage
zip(zipfile, files, flags = "-r9X", extras = "", zip = Sys.getenv("R_ZIPCMD", "zip"))
Arguments
- zipfile
- The pathname of the zip file: tilde expansion (see
path.expand
) will be performed. - files
- A character vector of recorded filepaths to be included.
- flags
- A character string of flags to be passed to the command: see Details.
- extras
- An optional character vector: see Details.
- zip
- A character string specifying the external command to be used.
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.
Value
-
The status value returned by the external command, invisibly.
