## Interactive folder selection using a native dialogue

### Description

Interactive folder selection using a native dialogue

### Usage

    fileBrowser(default = NULL, caption = NULL, multiple = FALSE,
      directory = FALSE)

### Arguments

`default` | Character: path to initial folder
`caption` | Character: caption on the selection dialogue
`multiple` | Boolean: allow to select multiple files?
`directory` | Boolean: allow to select directories instead of files?

### Details

Pltaform-dependent implementation:

- Windows: calls the `utils::choose.files` R function.

- macOS: uses AppleScript to display a folder selection dialogue. If `default` is `NA`, folder selection fallbacks to the default behaviour of the `choose folder` AppleScript command. Otherwise, paths are expanded with `path.expand`.

- Linux: calls the `zenity` system command.

If for some reason an error occurs (e.g. when using a remote server), the dialog fallbacks to an alternative, non-native file browser.

### Value

A length one character vector, character NA if 'Cancel' was selected.
