Extract files from or list a zip archive.
unzip(zipfile, files = NULL, list = FALSE, overwrite = TRUE,
junkpaths = FALSE, exdir = ".", unzip = "internal",
setTimes = FALSE)The pathname of the zip file: tilde expansion (see
path.expand) will be performed.
A character vector of recorded filepaths to be extracted: the default is to extract all files.
If TRUE, list the files and extract none. The
equivalent of unzip -l.
If TRUE, overwrite existing files, otherwise
ignore such files. The equivalent of unzip -o.
If TRUE, use only the basename of the stored
filepath when extracting. The equivalent of unzip -j.
The directory to extract files to (the equivalent of
unzip -d). It will be created if necessary.
The method to be used. An alternative is to use
getOption("unzip"), which on a Unix-alike may be set to the
path to a unzip program.
logical. For the internal method only, should the file times be set based on the times in the zip file? (NB: this applies to included files, not to directories.)
If list = TRUE, a data frame with columns Name
(character) Length (the size of the uncompressed file, numeric)
and Date (of class "POSIXct").
Otherwise for the "internal" method, a character vector of the
filepaths extracted to, invisibly.
unz to read a single component from a zip file.
zip for packing, i.e., the “inverse” of unzip();
further untar and tar, the corresponding
pair for (un)packing tar archives (“tarballs”) such as R
source packages.
