ahistory

An artifact which history is supposed to be reconstructed.
It will be converted into md5hash.

artifact

If <code>artifact</code> is not specified then <code>md5hash</code> is used.

md5hash

A character denoting an existing directory in which an artifact will be saved.

repoDir

A character denoting whether to print history in either a <code>"regular"</code> (default) way or like in a <code>"kable"</code> function.
See Notes.

format

Whether to provide hooks to objects like in <a rd-options="" href="/link/alink?package=archivist&version=2.1.2" data-mini-rdoc="archivist::alink">alink</a>. See examples.

alink

Further parameters passed to <a rd-options="" href="/link/alink?package=archivist&version=2.1.2" data-mini-rdoc="archivist::alink">alink</a> function. Used when <code>format = "kable"</code> and <code>alink = TRUE</code>.

<code>ahistory</code> extracts artifact's history and creates a data frame with 
history of calls and md5hashes of partial results. The overloaded 
<code>print.ahistory</code> function prints this history in a concise way. The overloaded
<code>print.ahistoryKable</code> function prints this history in the same way as <a rd-options="knitr" href="/link/kable?package=archivist&version=2.1.2&to=knitr" data-mini-rdoc="knitr::kable">kable</a>.
When <code>alink=TRUE</code> one can create history table/kable with hooks to partial results (artifacts) as in the <a rd-options="" href="/link/alink?package=archivist&version=2.1.2" data-mini-rdoc="archivist::alink">alink</a> function.

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.

ahistory function

This function is well explained on this <a href="http://r-bloggers.com/r-hero-saves-backup-city-with-archivist-and-github">http://r-bloggers.com/r-hero-saves-backup-city-with-archivist-and-github</a> blog post.

Demonstration

Whether to provide hooks to objects like in <a rd-options='' href='alink'>alink</a>. See examples.

Further parameters passed to <a rd-options='' href='alink'>alink</a> function. Used when <code>format = "kable"</code> and <code>alink = TRUE</code>.

<code>ahistory</code> extracts artifact's history and creates a data frame with 
history of calls and md5hashes of partial results. The overloaded 
<code>print.ahistory</code> function prints this history in a concise way. The overloaded
<code>print.ahistoryKable</code> function prints this history in the same way as <a rd-options='knitr' href='kable'>kable</a>.
When <code>alink=TRUE</code> one can create history table/kable with hooks to partial results (artifacts) as in the <a rd-options='' href='alink'>alink</a> function.
