restoreLibs

One of the following (see <a rd-options="" href="/link/aread?package=archivist&version=2.1.1" data-mini-rdoc="archivist::aread">aread</a>):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.

md5hash

Object with versions of packages to be installed. If not supplied then 
it will be extracted from md5hash <code> md5hash </code>

session_info

A character vector describing the location of <code>R</code> library trees to restore archived libraries, or <code>NULL</code>.
The default value of <code>NULL</code> corresponds to all libraries currently known to <a rd-options="" href="/link/.libPaths?package=archivist&version=2.1.1" data-mini-rdoc="archivist::.libPaths">.libPaths</a>(). 
Non-existent library trees are silently ignored.

lib.loc

Function <code> restoreLibs </code> gets either <code>session info</code> or artifact's <code>md5hash</code> 
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 <code>restoreLibs()</code> 
reverts all libraries that were attached previously to their previous versions.

Data exploration and modelling is a process in which a lot of data
artifacts are produced. Artifacts like: subsets, data aggregates, plots,
statistical models, different versions of data sets and different versions
of results. The more projects we work with the more artifacts are produced
and the harder it is to manage these artifacts. Archivist helps to store
and manage artifacts created in R. Archivist allows you to store selected
artifacts as a binary files together with their metadata and relations.
Archivist allows to share artifacts with others, either through shared
folder or github. Archivist allows to look for already created artifacts by
using it's class, name, date of the creation or other properties. Makes it
easy to restore such artifacts. Archivist allows to check if new artifact
is the exact copy that was produced some time ago. That might be useful
either for testing or caching.
