zip_process() returns an R6 class that represents a zip process.
It is implemented as a subclass of processx::process.
zip_process()
A zip_process R6 class object, a subclass of
processx::process.
zip_process classzp <- zip_process()$new(zipfile, files, recurse = TRUE,
poll_connection = TRUE,
stderr = tempfile(), ...)See processx::process for the class methods.
Arguments:
zipfile: Path to the zip file to create.
files: List of file to add to the archive. Each specified file
or directory in is created as a top-level entry in the zip archive.
recurse: Whether to add the contents of directories recursively.
include_directories: Whether to explicitly include directories
in the archive. Including directories might confuse MS Office when
reading docx files, so set this to FALSE for creating them.
poll_connection: passed to the initialize method of
processx::process, it allows using processx::poll() or the
poll_io() method to poll for the completion of the process.
stderr: passed to the initialize method of processx::process,
by default the standard error is written to a temporary file.
This file can be used to diagnose errors if the process failed.
... passed to the initialize method of processx::process.
