taf.unzip: Unzip File

In TAF: Transparent Assessment Framework for Reproducible Research

Unzip File

Description

Extract files from a zip archive, retaining executable file permissions.

Usage

taf.unzip(zipfile, files = NULL, exdir = ".", unzip = NULL, ...)

Arguments

zipfile	zip archive filename.
files	files to extract, default is all files.
exdir	directory to extract to, will be created if necessary.
unzip	extraction method to use, see details below.
...	passed to unzip.

Details

The default method unzip = NULL uses the external unzip program in Unix-compatible operating systems, but an internal method in Windows. For additional information, see the unzip help page.

Value

No return value, called for side effects.

Note

One shortcoming of the base unzip function is that the default "internal" method resets file permissions, so Linux and macOS executables will return a ⁠'Permission denied'⁠ error when run.

This function is identical to the base unzip function, except the default value unzip = NULL chooses an appropriate extraction method in all operating systems, making it useful when writing platform-independent scripts.

See Also

unzip is the base function to unzip files.
