Check where your package is installed

find.package("dplyr")

## [1] "C:/Program Files/R/R-4.0.3/library/dplyr"

All projects use the same library path. Then for each project, you need different library dependencies.

Intializing a project

renv::init()

A .Rprofile is created that forks the current R libraries.

Now, you can work as before. But the current state of packages would not change.

renv::snapshot()

The function tells you the current state of a project, and whether you can to update any packages in that project.

The lockfile is a JSON file that tells you packages installed in your project, versions, and sources.

This is useful for:

Time capsules (you can return to this project in the future without any unexpected changes)
Collaborative workflows (different people might have different packages installed).
Deployments (you can run your project remotely)

To restore the previously snapshot, you can use

renv::restore()

## * The library is already synchronized with the lockfile.
