renv
Overview
The renv package helps you create reproducible environments for
your R projects. Use renv to make your R projects more:
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 package 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 with a new or existing project. This
will set up your project with a private library, and also make sure to install
all of the packages you're using into that library. The packages used in your
project will be recorded into a lockfile, called renv.lock.
As you work in your project, you may need to install or upgrade different
packages. As these packages are installed, renv will automatically write
renv.lock for you. The renv.lock lockfile records the state of your project's
private library, and can be used to restore the state of that library as required.
Later, if you need to port your project to a new machine, you can call
renv::restore() to reinstall all of the packages as declared in the lockfile.
