grid.draw {grid}
Description
Produces graphical output from a graphical object.

Arguments
- x
- An object of class
"grob"or NULL. - recording
- A logical value to indicate whether the drawing operation should be recorded on the Grid display list.
Details
This is a generic function with methods for grob and gTree objects.
The grob and gTree methods automatically push any viewports in a vp slot and automatically apply any gpar settings in a gp slot. In addition, the gTree method pushes and ups any viewports in a childrenvp slot and automatically calls grid.draw for any grobs in a children slot.
The methods for grob and gTree call the generic hook functions preDrawDetails, drawDetails, and postDrawDetails to allow classes derived from grob or gTree to perform additional viewport pushing/popping and produce additional output beyond the default behaviour for grobs and gTrees.
Values
None.
See Also
grob.

grid.newpage() ## Create a graphical object, but don't draw it l <- linesGrob() ## Draw it grid.draw(l)
