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.
