zip: Compress Files into 'zip' Archives

Description

zip creates a new zip archive file.

Usage

zip(zipfile, files, recurse = TRUE, compression_level = 9)
zip_append(zipfile, files, recurse = TRUE, compression_level = 9)

Arguments

zipfile

The zip file to create. If the file exists, zip overwrites it, but zip_append appends to it.

files

List of file to add to the archive. Absolute path names will be added as absolute path names, relative path names stay relative in the archive.

recurse

Whether to add the contents of directories recursively.

compression_level

A number between 1 and 9. 9 compresses best, but it also takes the longest.

Value

The name of the created zip file, invisibly.

Details

zip_append appends compressed files to an existing 'zip' file.

Examples

# NOT RUN {
## Some files to zip up
dir.create(tmp <- tempfile())
cat("first file", file = file.path(tmp, "file1"))
cat("second file", file = file.path(tmp, "file2"))

zipfile <- tempfile(fileext = ".zip")
zip(zipfile, tmp)

## List contents
zip_list(zipfile)

## Add another file
cat("third file", file = file.path(tmp, "file3"))
zip_append(zipfile, file.path(tmp, "file3"))
zip_list(zipfile)
# }
