update: Update the contents to a zip/xlsx/ file.

In duncantl/RExcelXML: Tools for working with Excel XML documents

Update the contents to a zip/xlsx/ file.

Description

This function allows the caller to update the contents of a Zip archive, adding or overwriting existing entries within an archive, leaving others umodified.

It is often more convenient to use the [<- operator to add/update elements of an archive, e.g. archive[ c("a", "b") ] = list(I("Some text"), "myFile")

update currently works for zip files only, but it can be made generic and methods can be easily added for different types of archives (e.g. tar files) assuming the underlying functionality to add the files is available.

This function now (as of version 0.91-0 of this package) uses in-memory rather than temporary files and the external zip executable.

Usage

update(object, ...)

Arguments

object	the Excel xlsx file which is a ZipArchive object.
...	a collection of named values which give the contents to be added with those names.
