#Working with dependencies in R

#CRAN

#Using the DESCRIPTION file

For R projects, Johnny analyzes the DESCRIPTION file, which contains package metadata and dependency lists in the Depends, Imports, Suggests, and LinkingTo sections.

#Using the renv.lock file

The renv package is used to lock dependency versions:

1. Initialize renv in the project:

   renv::init()

2. Snapshot the dependency state:

   renv::snapshot()

A renv.lock file will be created, containing the locked versions of all dependencies.

#Dependency resolution via renv

Johnny supports dependency resolution for R projects with the --rlang-resolve flag. Resolution is performed using Rscript, so it must be available in the environment (the path can be overridden with the --rscript-path flag).
