## Dialog Boxes under Windows

### Description

Put up a Windows dialog box to communicate with the user. There are various types, either for the user to select from a set of buttons or to edit a string.

### Usage

    winDialog(type = c("ok", "okcancel", "yesno", "yesnocancel"),
              message)

    winDialogString(message, default)

### Arguments

`type` | character. The type of dialog box. It will have the buttons implied by its name.
`message` | character. The information field of the dialog box. Limited to 255 chars (by Windows, checked by R).
`default` | character. The default string.

### Value

For `winDialog` a character string giving the name of the button pressed (in capitals) or `NULL` (invisibly) if the user had no choice.

For `winDialogString` a string giving the contents of the text box when `Ok` was pressed, or `NULL` if `Cancel` was pressed.

### Note

The standard keyboard accelerators work with these dialog boxes: where appropriate `Return` accepts the default action, `Esc` cancels and the underlined initial letter (`Y` or `N`) can be used.

These functions are only available on Windows.
