basename {base}

R Documentation

Manipulate File Paths

Description

basename removes all of the path up to the last path separator (if any).

dirname returns the part of the path up to (but excluding) the last path separator, or "." if there is no path separator.

Usage

basename(path)
dirname(path)

Arguments

path	character vector, containing path names.

Details

For dirname tilde expansion is done: see the description of path.expand.

Trailing file separators are removed before dissecting the path, and for dirname any trailing file separators are removed from the result.

If an element of path is NA, so is the result.

Value

A character vector of the same length as path. A zero-length input will give a zero-length output with no error.

file.path, path.expand.

Examples

basename(file.path("","p1","p2","p3", c("file1", "file2")))
dirname(file.path("","p1","p2","p3","filename"))
