Rdz: Constructor for zipped R data archive

In omegahat/Rcompression: In-memory decompression for GNU zip and bzip2 formats

Constructor for zipped R data archive

Description

This is a constructor function that creates a "reference" to a file that represents a zipped archive of individual R objects saved in the archive. The resulting object can be indexed by name and a table of contents can be retrieved to find the names of the variables it contains.

This function returns an object of class RdzArchive which extends ZipFileArchive-class and is intended only to provide a mechanism to conver the elements to R objects.

Usage

Rdz(filename, check = TRUE, class = "RdzArchive")

Arguments

filename	the name of the file
check	argument passed to zipArchive to control whether the meta-data about the entries in the zip file is computed.
class	the class of the resulting object, typically unspecified

Value

An object of class RdzArchive-class.
