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)
A gTree object.
A gPath object. For grid.set this
specifies a grob on the display list. For setGrob this
specifies a descendant of the specified gTree.
A grob object.
A boolean indicating whether the gPath must be matched exactly.
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).
A logical value to indicate whether to redraw the grob.
setGrob returns a grob object; grid.set returns NULL.
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.
