Efficient Manipulation of 'Rd' Files and Help Topics R package rdtools version 0.1.0 Provides fast, cached lookup of help topics and aliases across installed, source, and in-development packages, plus efficient retrieval of parsed 'Rd' ('R' documentation) objects. Per-package indexes are built once and cached, making repeated retrieval cheap enough to call in a tight loop.
