R: Create Zip Archives

zip {utils}

R Documentation

Create Zip Archives

Description

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 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.
