Get package dependencies (offline)

Read a package's dependencies from file, rather than searching CRAN. Based on http://stackoverflow.com/a/30225680/1380598.

get_deps(path, dependencies = NA)

Arguments

path: A local file path to a package directory.
dependencies: Logical indicating whether to also install uninstalled packages which these packages depend on/link to/import/suggest (and so on recursively). Can also be a character vector, a subset of c("Depends", "Imports", "LinkingTo", "Suggests", "Enhances").
The default, NA, means c("Depends", "Imports", "LinkingTo"). TRUE means to use c("Depends", "Imports", "LinkingTo", "Suggests").

Value

A character vector of package dependencies.
