install.dependencies: Installing All Package Dependencies
In renozao/repotools: Tools for R Package Repositories

Install all dependencies from a package source directory or package source file.

1 2	install.dependencies(pkg, dependencies = NA, ..., verbose = TRUE, dry.run = FALSE)

`pkg`	package name, path or source file
`dependencies`	logical indicating whether to also install uninstalled packages which these packages depend on/link to/import/suggest (and so on recursively). Not used if `repos = NULL`. Can also be a character vector, a subset of `c("Depends", "Imports", "LinkingTo", "Suggests", "Enhances")`. Only supported if `lib` is of length one (or missing), so it is unambiguous where to install the dependent packages. If this is not the case it is ignored, with a warning. The default, `NA`, means `c("Depends", "Imports", "LinkingTo")`. `TRUE` means to use `c("Depends", "Imports", "LinkingTo", "Suggests")` for `pkgs` and `c("Depends", "Imports", "LinkingTo")` for added dependencies: this installs all the packages needed to run `pkgs`, their examples, tests and vignettes (if the package author specified them correctly). In all of these, `"LinkingTo"` is omitted for binary packages.
`...`	extra arguments passed to `install.pkgs`.
`verbose`	verbosity level (logical or numeric)
`dry.run`	logical that indicates if one should only return the computed set of packages and dependencies to install. If `NULL`, then it is internally set to `TRUE` only when there is a mismatch between the requested and the OS binary package types (e.g., if `type = 'win.both'` on a Unix/Mac host).
