winMenus {base}R Documentation

User Menus under Windows

Description

Enables users to add, delete and program menus under Windows.

Usage

winMenuAdd(menuname)
winMenuAddItem(menuname, itemname, action)
winMenuDel(menuname)
winMenuDelItem(menuname)

Arguments

menuname a character string naming a menu.
itemname a character string naming a menu item on an existing menu.
action a character string describing the action when that menu is selected, or "enable" or "disable".

Details

User menus are added to the right of existing menus, and items are added at the bottom of the menu.

By default the action character string is treated as R input, being echoed on the command line and parsed and executed as usual.

Specifying an existing item in winMenuAddItem enables the action to be changed.

Submenus can be specified by separating the elements in menuname by slashes: as a consequence menu names may not contain slashes.

If the action is specified as "none" no action is taken: this can be useful to reserve items for future expansion.

Value

NULL, invisibly. If an error occurs, an informative error message will be given.
