Require package namespaces
requireNamespaces(packages)

This function intentionally does not attach packages, unlike library,
require, or attachNamespace functions.
Intended for use inside package functions that relying upon optional
dependencies defined via Suggests instead of Imports or Depends in
DESCRIPTION file.
Unlike requireNamespace, this variant always errors on namespace failure.
