rv: A Reproducible, Fast, and Declarative Way to Manage R Packages

rv is a revolutionary R package manager that allows you to manage and install R packages in a reproducible, fast, and declarative way. By specifying the R version, repositories, and dependencies in a configuration file (rproject.toml), the `rv sync` command synchronizes the library, configuration file, and lock file, while `rv plan` provides a preview. It supports custom package and repository settings, allowing for the installation of specific packages and their suggested packages. rv is written in Rust and comes with detailed installation and usage documentation.
