Fortunately Devtools provides an easy solution: install_deps()

install_deps(pkg = ".", dependencies = logical, threads = getOption("Ncpus",1))

Arguments:
pkg: package description, can be path or package name. See ‘as.package’ for more information

dependencies: ‘logical’ indicating to also install uninstalled packages which this ‘pkg’ depends on/links to/suggests. See argument ‘dependencies’ of ‘install.packages’.

threads: number of concurrent threads to use for installing dependencies. It defaults to the option ‘"Ncpus"’ or ‘1’ if unset.

Examples:

install_deps(".")  
install_deps("/path/to/package",dependencies="logical")
