Cross-Platform ‘zip’ Compression
Stable version:
Development version:
zip() creates a new ZIP archive. (It overwrites the output file if it exists.) Simply supply all directories and files that you want to include in the archive.
It makes sense to change to the top-level directory of the files before archiving them, so that the files are stored using a relative path name.
zip("sources.zip", c("R", "src"))
file.info("sources.zip")
#> size isdir mode mtime ctime
#> sources.zip 580179 FALSE 644 2023-04-17 13:49:31 2023-04-17 13:49:31
#> atime uid gid uname grname
#> sources.zip 2023-04-17 13:49:31 501 20 gaborcsardi staffDirectories are added recursively by default.
zip_append() is similar to zip(), but it appends files to an existing ZIP archive.
zip_list() lists files in a ZIP archive. It returns a data frame:
zip_list("sources.zip")

You can use the zip_process() and unzip_process() functions to create background zip / unzip processes. These processes were implemented on top of the processx::process class, so they are pollable.
