| grid.set {grid} | R Documentation | 
Replace a grob or a descendant of a grob.
grid.set(gPath, newGrob, strict = FALSE, grep = FALSE, redraw = TRUE) setGrob(gTree, gPath, newGrob, strict = FALSE, grep = FALSE)
gTree | 
A gTree object. | 
gPath | 
A gPath object. For grid.set this
specifyies a grob on the display list.  For setGrob this
specifies a descendant of the specified gTree.  | 
newGrob | 
A grob object. | 
strict | 
A boolean indicating whether the gPath must be matched exactly. | 
grep | 
A boolean indicating whether the gPath should
be treated as a regular expression.  Values are recycled across
elements of the gPath (e.g., c(TRUE, FALSE) means
that every odd element of the gPath will be treated as
a regular expression).
 | 
redraw | 
A logical value to indicate whether to redraw the grob. | 
setGrob copies the specified grob and returns a modified
grob.
grid.set destructively replaces a grob on the display list.
If redraw
is TRUE it then redraws everything to reflect the change.
These functions should not normally be called by the user.
setGrob returns a grob object;  grid.set returns NULL.
