R CMD checkすると、ドキュメントの存在しない関数は警告がでるのだけど、パッケージ内部で使うための関数も引っかかってしまう。
if a package pkg contains user-level objects which are for “internal” use only, it should provide a file pkg-internal.Rd which documents all such objects, and clearly states that these are not meant to be called by the user.
gridのRdを読めと書いてあったので読んでみる(R-2.11.0/src/library/grid/man/grid-internal.Rd)。
