Keywords
dplot
##### Usage
grid.remove(gPath, warn = TRUE, strict  =  FALSE, grep = FALSE, global = FALSE, allDevices = FALSE, redraw = TRUE)
grid.gremove(..., grep = TRUE, global = TRUE)
removeGrob(gTree, gPath, strict = FALSE, grep = FALSE, global = FALSE, warn = TRUE)
##### Arguments
gTree
A gTree object.
gPath
A gPath object. For grid.remove this specifies a gTree on the display list. For removeGrob this specifies a descendant of the specified gTree.
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).
global
A boolean indicating whether the function should affect just the first match of the gPath, or whether all matches should be affected.
allDevices
A boolean indicating whether all open devices should be searched for matches, or just the current device. NOT YET IMPLEMENTED.
warn
A logical to indicate whether failing to find the specified grob should trigger an error.
redraw
A logical value to indicate whether to redraw the grob.
...
Arguments that are passed to grid.get.
##### Details

removeGrob copies the specified grob and returns a modified grob.

grid.remove destructively modifies a grob on the display list. If redraw is TRUE it then redraws everything to reflect the change.

grid.gremove (g for global) is just a convenience wrapper for grid.remove with different defaults.

##### Value

removeGrob returns a grob object; grid.remove returns NULL.

grob, getGrob, removeGrob, removeGrob.
