restoreLibs: Restore Versions of Libraries

Description Usage Arguments Contact Author(s) References See Also Examples

View source: R/restoreLibraries.R

Description

Function restoreLibs gets either session info or artifact's md5hash and restore libraries/packages to versions attached when the object was saved in the repo. Typical use case is following. We have saved an object and now we are restoring it, but with current version of packages something is not working. The function restoreLibs() reverts all libraries that were attached previously to their previous versions.

Usage

restoreLibs(md5hash, session_info = NULL, lib.loc = NULL)

Arguments

md5hash

One of the following (see aread):

A character vector which elements are consisting of at least three components separated with '/': Remote user name, Remote repository and name of the artifact (MD5 hash) or it's abbreviation.

MD5 hashes of artifacts in current local default directory or its abbreviations.
