Description

Finds the full file names of files in packages etc.

Usage

system.file(..., package = "base", lib.loc = NULL, pkg, lib)

Arguments

...	character strings, specifying subdirectory and file(s) within some package. The default, none, returns the root of the package. Wildcards are not supported.
package	a character string with the name of a single package. An error occurs if more than one package name is given.
lib.loc	a character vector with path names of R libraries, or NULL. The default value of NULL corresponds to all libraries currently known. If the default is used, the loaded packages are searched before the libraries.
pkg	previous name for argument package. Deprecated.
lib	previous name for argument lib.loc. Deprecated.

Value

A character vector of positive length, containing the file names that matched ..., or the empty string, "", if none matched. If matching the root of a package, there is no trailing separator.

As a special case, system.file() gives the root of the base package only.
