grid.set(gPath, newGrob, strict = FALSE, grep = FALSE, redraw = TRUE)
setGrob(gTree, gPath, newGrob, strict = FALSE, grep = FALSE)grid.set this
specifies a grob on the display list. For setGrob this
specifies a descendant of the specified gTree. 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).
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.
These functions should not normally be called by the user.
