groundhog: Version-Control for CRAN, GitHub, and GitLab Packages
Make R scripts reproducible, by ensuring that
every time a given script is run, the same version of the used packages are
loaded (instead of whichever version the user running the script happens to
have installed). This is achieved by using the command
groundhog.library() instead of the base command library(), and including a
date in the call. The date is used to call on the same version of the
package every time (the most recent version available at that date).
Load packages from CRAN, GitHub, or Gitlab.
Note: groundhog relied on Microsoft's MRAN archive which is being discontinued.
This version of groundhog is transitioning away from MRAN, relying on it only for
dates prior to Jan 31, 2023. A future release of groundhog, v2.3.0,
expected by May 2023, will discontinue relying on MRAN entirely.
