Add a grob to a gTree or a descendant of a gTree.
grid.add(gPath, child, strict = FALSE, grep = FALSE,
global = FALSE, allDevices = FALSE, redraw = TRUE)addGrob(gTree, child, gPath = NULL, strict = FALSE, grep = FALSE,
global = FALSE, warn = TRUE)
setChildren(x, children)
A gTree object.
A gPath object. For grid.add this
specifies a gTree on the display list. For addGrob this
specifies a descendant of the specified gTree.
A grob object.
A gList 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 boolean indicating whether the function should affect
just the first match of the gPath, or whether all matches
should be affected.
A logical to indicate whether failing to find the specified gPath should trigger an error.
A boolean indicating whether all open devices should be searched for matches, or just the current device. NOT YET IMPLEMENTED.
A logical value to indicate whether to redraw the grob.
addGrob returns a grob object; grid.add returns NULL.
addGrob copies the specified grob and returns a modified
grob.
grid.add destructively modifies a grob on the display list.
If redraw
is TRUE it then redraws everything to reflect the change.
setChildren is a basic function for setting all children
of a gTree at once (instead of repeated calls to addGrob).
grob, getGrob,
addGrob, removeGrob.
