Install Packages from Snapshots on the Checkpoint Server for
Reproducibility
The goal of checkpoint is to solve the problem of package
reproducibility in R. Specifically, checkpoint allows you to install
packages as they existed on CRAN on a specific snapshot date as if you had
a CRAN time machine.  To achieve reproducibility, the checkpoint() function
installs the packages required or called by your project and scripts to a
local library exactly as they existed at the specified point in time. Only
those packages are available to your project, thereby avoiding any package
updates that came later and may have altered your results. In this way,
anyone using checkpoint's checkpoint() can ensure the reproducibility of
your scripts or projects at any time. To create the snapshot archives, once
a day (at midnight UTC) Revolution Analytics refreshes the Austria CRAN mirror, on the "Managed
R Archived Network" server (http://mran.revolutionanalytics.com/).
Immediately after completion of the rsync mirror process, the process takes a
snapshot, thus creating the archive. Snapshot archives exist starting from
2014-09-17.
