Project Environments.

renv

Overview

The renv package[^1] helps you create reproducible environments for your R projects. Use renv to make your R projects more isolated, portable and reproducible.

• Isolated: Installing a new or updated package for one project won’t break your other projects, and vice versa. That’s because renv gives each project its own private library.
• Portable: Easily transport your projects from one computer to another, even across different platforms. renv makes it easy to install the packages your project depends on.
• Reproducible: renv records the exact package versions you depend on, and ensures those exact versions are the ones that get installed wherever you go.

Installation

Install the latest version of renv from CRAN with:

install.packages("renv")

Workflow

Use renv::init() to initialize renv in a new or existing project. This will set up a project library, containing all the packages you’re currently using. The packages (and all the metadata needed to reinstall them) are recorded into a lockfile, renv.lock, and a .Rprofile ensures that the library is used every time you open that project.

As you continue to work on your project, you will install and upgrade packages, either using install.packages() and update.packages or renv::install() and renv::update(). After you’ve confirmed your code works as expected, use renv::snapshot() to record the packages and their sources in the lockfile.

Later, if you need to share your code with someone else or run your code on new machine, your collaborator (or you) can call renv::restore() to reinstall the specific package versions recorded in the lockfile.
