Details

what can specify one of several different sources of documentation, including the R manuals (R-admin, R-data, R-exts, R-intro, R-ints, R-lang), NEWS, COPYING (the GPL licence), any of the licenses in ‘share/licenses’, FAQ (also available as R-FAQ), and the files in ‘R_HOME/doc’.

Only on Windows, the R for Windows FAQ is specified by rw-FAQ.

If package is supplied, documentation is looked for in the ‘doc’ and top-level directories of an installed package of that name.

The documentation types are tried in turn starting with the first specified in type (or "pdf" if none is specified).
