Description:
A single key function, 'Require' that makes rerun-tolerant
versions of 'install.packages' and `require` for CRAN packages, packages
no longer on CRAN (i.e., archived), specific versions of packages,
and GitHub packages. This approach is developed to create reproducible
workflows that are flexible and fast enough to use while in development stages,
while able to build snapshots once a stable package collection is found.
As with other functions in a reproducible workflow, this package
emphasizes functions that return the same result whether it is
the first or subsequent times running the function, with subsequent times being
sufficiently fast that they can be run every time without undue waiting burden on
the user or developer.
