The renv package is a new effort to bring private project-local R libraries to your projects. The goal is for renv to be a robust, stable replacement for the Packrat package, with fewer surprises and better default behaviors.

The general workflow when working with renv is:

1. Call renv::init() to initialize a new project-local environment, with a private R library;

2. Work in the project as normal, installing and removing new R packages as they are needed in the project,

3. Call renv::snapshot() to save the state of the project library to the lockfile (called renv.lock),

4. Call renv::restore() to restore the state of the project library, based on the state of the lockfile previously generated by renv::snapshot().
