Remove a Grid Graphical Object

Description

Remove a grob from a gTree or a descendant of a gTree.

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 `logical` indicating whether the `gPath` must be matched exactly.
`grep`	a `logical` 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 `logical` indicating whether the function should affect just the first match of the `gPath`, or whether all matches should be affected.
`allDevices`	a `logical` 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 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.
