grid.add | R Documentation |
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)
gTree, x |
A gTree object. |
gPath |
A gPath object. For |
child |
A grob object. |
children |
A gList object. |
strict |

grep |

addGrob

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
).
addGrob
returns a grob object; grid.add
returns NULL
