Restore Versions of Libraries

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.

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.
session_info	Object with versions of packages to be installed. If not supplied then it will be extracted from md5hash md5hash
lib.loc	A character vector describing the location of R library trees to restore archived libraries, or NULL. The default value of NULL corresponds to all libraries currently known to .libPaths(). Non-existent library trees are silently ignored.

Examples

# NOT RUN {
## objects preparation
## be aware! this will probably downgrade many of your libraries
