r-checkpoint

Description

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.
