[R-SIG-Mac] Create custom menus in R

[Philippe Bouchet]

Dear list members,

Does anyone know how to add items to the menu bar in R ?
Certain packages have their own custom menus, which allow access to different functions, but I haven't been able to figure out what the trick was with these.
I have been looking at GUI interface packages such as fgui and the like but in vain.

Any help or suggestions greatly appreciated !
