R: Set a Grid Graphical Object

grid.set {grid} | R Documentation

## Set a Grid Graphical Object

### Description

Replace a grob or a descendant of a grob.

### Usage

    grid.set(gPath, newGrob, strict = FALSE, grep = FALSE,
             redraw = TRUE)

    setGrob(gTree, gPath, newGrob, strict = FALSE, grep = FALSE)

### Arguments

`gTree` | A gTree object.
`gPath` | A gPath object. For `grid.set` this specifies a grob on the display list. For `setGrob` this specifies a descendant of the specified gTree.
`newGrob` | A grob object.
`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).
`redraw` | A logical value to indicate whether to redraw the grob.

### Details

`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.

### Value

`setGrob` returns a grob object; `grid.set` returns `NULL`.
