R: Expand File Paths

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

On some Unix builds of R, a leading `~user` will expand to the home directory of `user`, but not on Unix versions without `readline` installed, nor if R is invoked with --no-readline.

In an interactive session `capabilities("cledit")` will report if `readline` is available.

### See Also

`basename`, `normalizePath`.

### Examples

    path.expand("~/foo")
