Value

Function call (of class "extplotmath" - just to make it somewhat special and different from expressions) to internal grid.annotation's function bullet(pch,size,gp), which is evaluated when the grid.annotation is to be redrawn. bullet draws a symbol pch with size size and grid graphical parameters (see gpar) gp at the "current position" inside the grid.annotation.
