winDialog Dialog Boxes under Windows

Description

On MS Windows only, put up a 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.
