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.
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.
