winDialog | R Documentation |
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.
winDialog(type = c("ok", "okcancel", "yesno", "yesnocancel"), message) winDialogString(message, default)
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. |
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.
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.
