unzip: Extract or List Zip Archives


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 (the equivalent of unzip -o), otherwise ignore such files (the equivalent of unzip -n).


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.
