grid.draw
Draw a grid grob
Description
Produces graphical output from a graphical object.
Usage
grid.draw(x, recording=TRUE)
Arguments
x | An object of class |
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.
Value
None.
