"""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) Microsoft refreshes the Austria CRAN mirror on the "Microsoft
R Archived Network" server (<https://mran.microsoft.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."""
