RShowDoc(what, type = c("pdf", "html", "txt"), package)


what a character string: see Details.
type an optional character string giving the preferred format.
package an optional character string specifying the name of a package within which to look for documentation.


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), FAQ (also available as R-FAQ), and the files in ‘R_HOME/doc’.

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

If what is missing a brief usage message is printed.

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