Groundhog: Addressing the Threat That R Poses to Reproducible Research

Correct me if I'm wrong but specifying an older package version in R still pulls the newest packages from CRAN for any dependencies, which is quick way to run into a load of incompatibilities.

I've not tried renv yet but packrat was a pretty poor solution.

If you need to use an older version of a package and don’t have a packrat/renv lockfile already, then packrat/renv are not going to help you. mran/checkpoint could though.

I agree packrat (which I created) was a poor solution for most users. renv is far better and more usable.

You can specify version numbers in renv, you take snapshots of your dependencies into a lock file and can always restore from there or make a new snapshot.
