Installing and Loading R Packages for Reproducible Workflows
Set .libPaths
Setup for binary Linux repositories
Create a custom "available.packages" object
Needs VersionOnRepos, versionSpec and inequality columns
Available and archived versions
The default cache directory for Require Cache
Path to (package) cache directory
Get the option for Require.cachePkgDir
Purge everything in the Require cache
Creates the directories, and adds version number
Check directory path
Pass through function for chooseCRANmirror
Clear Require Cache elements
Compare package versions
Only checks for deprecated libPath argument (singular)
GitHub package tools
Detach and unload all packages
Deals with missing libPaths arg, and takes first

Update installed packages with latest available versions
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.
