path.expand {base}R Documentation

Expand File Paths

Description

Expand a path name, for example by replacing a leading tilde by the user's home directory (if defined on that platform).

Usage

path.expand(path)

Arguments

path

character vector containing one or more path names.

Details

(These details are for a Unix-alike: the details differ on Windows.)

On most builds of R a leading ~user will expand to the home directory of user, but not on builds without readline installed. (In an interactive session capabilities("cledit") will report if readline is available.)

The ‘path names’ need not exist nor be valid path names but they do need to be representable in the session encoding.

Value

A character vector of possibly expanded path names: where the home directory is unknown or none is specified the path is returned unchanged.

See Also

basename, normalizePath.

Examples

path.expand("~/foo")
