R: Find Names of R System Files

system.file {base} | R Documentation

## Find Names of R System Files

### 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.

### Examples

    system.file()                # The root of the `base' package
    system.file(package = "lqs") # The root of package `lqs'
    system.file("INDEX")
    system.file("help", "AnIndex", package = "stepfun")
