ignored.packages: A vector of packages, which should be ignored when attempting to snapshot the project's private library. Note that if a package has already been added to the lockfile, that entry in the lockfile will not be ignored.
external.libraries: A vector of library paths, to be used in addition to the project's own private library. This can be useful if you have a package available for use in some global library, but for some reason renv is not able to install that package (e.g. sources or binaries for that package are not publicly available, or you have been unable to orchestrate the pre-requisites for installing some packages from source on your machine).
use.cache: Use a global cache of R packages. When active, renv will install packages into a global cache, and link packages from the cache into your renv projects as appropriate. This can greatly save on disk space and install time when for R packages which are used across multiple projects in the same environment.

It is possible to provide your own global defaults for these options. See config for more details. This can be useful if you'd like to enforce certain project settings within new projects.
