Different ways of creating lockfile

teal leverages renv::snapshot(), which offers multiple methods for lockfile creation.

• Working directory lockfile: teal, by default, will create an implicit type lockfile that uses renv::dependencies() to detect all R packages in the current project's working directory.

• DESCRIPTION-based lockfile: To generate a lockfile based on a DESCRIPTION file in your working directory, set renv::settings$snapshot.type("explicit"). The naming convention for type follows renv::snapshot(). For the "explicit" type, refer to renv::settings$package.dependency.fields() for the DESCRIPTION fields included in the lockfile.

• Custom files-based lockfile: To specify custom files as the basis for the lockfile, set renv::settings$snapshot.type("custom") and configure the renv.snapshot.filter option.

lockfile usage

After creating the lockfile, you can restore the application's environment using renv::restore().
